Hey all
I am playing around with some redistribution and route manipulation (from Workbook 4 Lab 3, Task 4)
I have configured R1 to lower the distance to 105 for ospf LSA's specifically from router 2 (150.1.2.2) but it seems to include the same route that was advertised back fom R3 which is causing a feedback loop:
Rack1R1#show ip ospf data external 150.1.2.0
OSPF Router with ID (150.1.1.1) (Process ID 1)
Type-5 AS External Link States
Routing Bit Set on this LSA
LS age: 1385
Options: (No TOS-capability, DC)
LS Type: AS External Link
Link State ID: 150.1.2.0 (External Network Number )
Advertising Router: 150.1.2.2
LS Seq Number: 8000001A
Checksum: 0x80D1
Length: 36
Network Mask: /24
Metric Type: 2 (Larger than any link state path)
TOS: 0
Metric: 20
Forward Address: 0.0.0.0
External Route Tag: 0
