Dears,
I have seen that we point Next-Hop to R1 in Router#3.If we do not do it , packet go to SW1 and dont reach.
In normal cases/previous Tasks we always do next-hop self on Border Routers and in Transit router we did not change next-hop in the the Transit Routers.
So If we delete the command in R3 which is point next hop as below.
no neighbor 155.1.13.1 route-map NEXTHOP in
Then the AS 54 routes 112.X.X.X points to Next-Hop 155.1.146.4 ..
Rack1R3#sh ip bgp //Ommited
*>i112.0.0.0 155.1.146.4 0 100 0 54 50 60 i
In addition to above we have configure EIGRP and advertising 155.1.X.X on all internal R1-R6 and SW1 and SW4
router eigrp 100
network 155.1.0.0
no auto-summary
So its mean R3 should reach 155.1.146.4 since its known/reachable via IGP .Then Why still we are chaging the Next-Hop.
Appreciate to support.
Thanks
