Hello community, I'm just so confused with these commands as somehow they seem to do the same thing (filter) but not quite sure how they differ, is anyone able to help me understand please?
R5(config)#do sh run | i ip pim
ip pim rp-address 150.1.5.5 1 ---> 1) R5 is willing to be the RP for groups defined by ACL 1 only
ip pim accept-rp 150.1.5.5 2 ---> 2) R5 will accept join messages for groups defined by ACL 2 only
ip pim accept-register list 100 ---> 3) R5 will accept register messages for groups defined by ACL 100 only
R5(config)#do sh access-l 1
Standard IP access list 1
10 permit 224.0.0.0, wildcard bits 0.255.255.255 (623 matches)
R5(config)#do sh access-l 2
Standard IP access list 2
10 permit 224.110.110.110
20 permit 224.10.10.10 (142 matches)
R5(config)#do sh access-l 100
Extended IP access list 100
10 deny ip host 155.1.146.1 any
20 deny ip host 155.1.146.7 any
30 deny ip host 155.1.146.4 any
40 permit ip any any (23 matches)
- If I already have R5 decide what groups to serve as RP, what's the point of having 2) or 3)?
- If I already have R5 deciding who to accept join messages from, what's the point of having 1) or 3)?
- If I already have R5 deciding who to accpet register messages from, what's the point of having 2) or 3)?
Are these three commands used seperately as either 1) or 2) or 3) to achieve filtering or do you use them in conjuction to achieve filtering? I'm confused :(
