I am have the attached diagram:
- There is two links between routers.
- I have intiate BGP Session between them. for incoming traffic I use prepend and it worked fine.
Now, my objective to use the BGP to route network 10.8.8.0/29 on link -1 and network 10.10.10.0/29 on Link-2 on normal operation. In case Link one down I want to route network 10.8.8.0/29 to the second link. In case link-2 down, network 10.10.10.0/29 should be routed to link-1.
Which attribute I should use for this and how this can be acheived to deal with the source IP.
The failover will work without IP SLA if you shutdown the interface on the internal router. You need IP SLA if you want to test the entire path between the two routers. For instance, if the external router fails, the internal router will not know since it is connected to the switch and not directly to the internal router. That is where IP SLA can help.
