I am trying to create a BGP simulation in GNS3.
I have the following topology
Here's what I have understood:
R1 will advertise 18.104.22.168
R2 will advertise 22.214.171.124
R3 will advertise 126.96.36.199
R4 will advertise 188.8.131.52, 184.108.40.206, 220.127.116.11
Since, the next hop is not changed in iBGP sessions, I will either have to use
neighbor next-hop-self command or add IGP.'
I am adding IGP. In AS 200 for R3 I will have to add 18.104.22.168 and 22.214.171.124. Similarly for R2 I will have to add 126.96.36.199 and 188.8.131.52.
If I choose to add RIP or OSPF with same process ID in AS 200 and AS 300 then doing IGP will share the routing information of AS 200 and AS 300 with each other using IGP. How do I fix this?
