Have an interesting scenario as part of a network migration.  One where the network is split into the default vrf and a new VRF.  The situation arises that the PC access vlan SVI will be in one VRF while the voice VLAN SVI is assigned to the other VRF.  PC plugs into the phone switch.  Routing between the VRF's is functioning via a FW. Trying to imagine how this would cause issues for VoIP calls, if any.  As long as the IP phone is still able to register with it's call manager in the appropriate VRF I don't see how this would cause issues. Am I missing something?  Thanks.

hey guys - I was going to do some investigating - I'm really weak on Multicast - in fact, it's my weakest topic - I use MPLS, QOS, and most of the other technologies but I almost feel like I'm at square one on multicast

I'm thinking of diving into the ATC - I have Beau Williamson's book, but I'd like to know if there isn't a better way to look at this topic instead of diving right into the ATC's - the Deep dives or some of the early CCNA/CCNP multicast videos

Thought I'd ask in case anyone else is in my predictment

I've been getting these mixed up, so maybe this will help someone too:

Incremental SPF - iSPF - Calcs SPF only on what changed. Topological changes (small/minor). 
Ex: New Stub router add, Link failure of link not part of Shortest Path Tree (SPF uses RIDs to calc SPT).

Partial SPF - PRC - Partial Route Calcs - Add/delete/metric change of prefixes (NLRI). No change to SPT. No link changes.
LSAs (those that carry prefix info!): 3, 4, 5, 7 
Ex: External route changes (external to an AREA, NOT just OSPF E1/E2/N1/N2... they weren't very clear on this).
Bonus Pt: Using Redistribution to bring route info into OSPF vs. Intra Area, within an Area. Option to scale single Area OSPF. Less Type 1 and 2 LSAs.

Full - Changes (major) to SPT, must do Full SPF Calc.
LSAs: 1, 2 
Ex: Metric change of link that would cause SPT to change (that would require Calc of alternate links, meaning not a Stub router). 

 

IS-IS does it a little bit differently, more like OSPFv3, but I'm still new to IS-IS, so I'll leave that for someone else to add to for now.
Thanks!

After watching Brian's ATC video on OSPF Areas and LSAs I thought I was finally clear on how OSPF will pick the exit point for external prefixes - intra-area external are preferred over inter-area external...or so I thought.

I did a quick and dirty topology: R3 ---- R4 ---- R5 ---- R6

R3 and R4 e0/0 are in Area 0

R4 e0/1 and R5 and R6 are in Area 1

R3 and R6 are both redistributing prefix 172.16.100.0/24 using default Type 2 and metric 20

Based on what I was hearing from Brian I would expect R5 to always choose R6 as the exit point to reach the external prefix due to the fact that R5 has a Router LSA for R6 which means they are in the same area.

When everything comes up and the SPF has been run I expect R5 to use R6 as the next hop, which it does:

Routing entry for 172.16.100.0/24

  Known via "ospf 1", distance 110, metric 20, type extern 2, forward metric 10

  Last update from 10.1.56.6 on Ethernet0/0, 00:18:37 ago

  Routing Descriptor Blocks:

  * 10.1.56.6, from 6.6.6.6, 00:18:37 ago, via Ethernet0/0

      Route metric is 20, traffic share count is 1

I would expect that I could raise the OSPF cost of e0/0 on R5 to 1000 and it should still use R6 as the exit point, but it does not it switches over to using R3:

Routing entry for 172.16.100.0/24

  Known via "ospf 1", distance 110, metric 20, type extern 2, forward metric 20

  Last update from 10.1.45.4 on Ethernet0/1, 00:00:01 ago

  Routing Descriptor Blocks:

  * 10.1.45.4, from 3.3.3.3, 00:00:01 ago, via Ethernet0/1

      Route metric is 20, traffic share count is 1

Then I started to do a little research and found that the intra-area external over inter-area external preference is only honored if both of the following conditions are true:

1) The router is running in rfc 2328 compatibility mode instead of rfc 1583 compatibility

2) The intra-area ASBR needs to be in a non-backbone area

RFC1583 compatibility just uses the best cost to reach the closest ASBR. I wonder if the CSR1000v routers that Brian was using during the ATC recording run rfc2328 out of the box to make the path selection do what he says in the video?

I run a lot of Juniper in my environment and when I saw one of my core switches preferring an inter-area ASBR over an intra-area ASBR to reach some external prefixes I was quite perplexed as to why. Now I know...I think :-)

hi everyone 

iam into this lecture  with mr keith bogart into ccnpv2 lectures :-

EIGRP Metric Manipulation -- Part 1

 note :- line with red i draw with myself

 

1- r18 will adv 188.188.188.0 to r19 , then r19 will adv it to Rx to r20

notice that r20 have  same network 188.188.188.0 as directly connected network

does r20 will adv network 188.188.188.0 directly cnnected to r19 , or will adv network 188.188.188.0 that he rcv via rx 

or r20 will adv both networks ?

i hope to undersanding my question

 

thanks

Hi all,

I have a "beginner" question for you.

When I see rates on different show outputs like these ones:

AA#sh policy-map int FastEthernet0/0/0.2 input | i offered
      30 second offered rate 3933000 bps
      30 second offered rate 6302000 bps
      30 second offered rate 4761000 bps
      30 second offered rate 4776000 bps, drop rate 0000 bps
AA#sh int FastEthernet0/0/0 | i 30 sec
  30 second input rate 19753000 bits/sec, 1629 packets/sec
  30 second output rate 0 bits/sec, 0 packets/sec

How is the rate calculated? Does it take into consideration the full bits put on the wire (L2+L3+L4+Payload)? Or it just looks at everything above L2? Or above L3?

Did not manage to find info about this on google.

Hello, 

 

I have 2x questions I am hoping to get some help with. Both involve OSPF NSSA areas with multiple exit points and traffic engineering by controlling which ABR performs translation

 

The first question i have is how does the "area [#] nssa translate type7 always" work when configured on an ABR and there are multiple ABRs present. When I say 'work' I generally maybe hopefully understand a little about what this command does in term of 7/5 translation and how that can be used for TE. What i don’t understand and cannot seem to find any information or a clear explanation on is the magic that makes this command work. What signaling or communication takes place that allows 1 ABR to assert itself over the other? 

The second question i have again relates to the "area [#] nssa translate type7 always" command with an NSSA area that has multiple exit ports. I have the preferred method is to modify the RIDs on the ABRs if you need to perform any TE as the "area [#] nssa translate type7 always" is unreliable. 

 

 

Any thoughts ore feedback on either question would be greatly appreciated.

Hello Everyone,

I have a little confusion. I am doing EIGRP Labs and in "EIGRP Summarization Lab" we have configured the summary address of connected loopbacks on both interfaces of R4 (one is connecting to R5  over VLAN 45 and other is over DMVPN Cloud)

But now in in next Task which is "IEGRP Summarization with Default Routing" we are configuring the summary 0.0.0.0 0.0.0.0 only over DMVPN interface, not on the VLAN 45 Interface?

Hello to everybody.

Thank you INE for offering this place on the Internet.

I am trying to make a career change and targeting an entry role, hopefully a network position, in England. I am currently studying towards my CCNP in Routing and Switching and as soon as I finish I will look to get into work.

I am wondering if there's any CCIE that coul be interested to spend twenty minutes of his time, I am willing to pay for it, to help a noob to make his head around the Telecommunication industry in the UK.

I would like to have an advice regarding the followings:

 

1. Recruitment companies to consider
2. Tips for the technical interview
3. Companies to apply to (ISP, Data Centers...anything that can get me closer to what I want to do)
4. Salary expectations.

 

I look forward to hearing from you.

 

Kind Regards.

I went to R6 and enabled redistribution of BGP into RIPng ... 

ipv6 router rip CCIE

 timers 10 30 30 40

 redistribute bgp 65006 metric 3

This propagated the ipv6 route into the RIP table and I was able to ping.
 

R3#ping 2004:4:2:2::1 so lo0

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2004:4:2:2::1, timeout is 2 seconds:

Packet sent with a source address of ::192:122:3:3

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 5/5/7 ms
 

Seems to me like this is the easiest solution. Am I missing something or violating any restrictions by just redistributing BGP into RIP?
