Hi Scott,
I used TTL-security instead of ebgp multihop. But having issue with
the next hop being inaccessible for the routes and routes are not
selected as best routes. See below the config for both the routers. I
am using EIGRP for loopback connectivity between the routers. See
below the output for the received routes.
Nakiska#sh ip bgp
BGP table version is 5, local router ID is 10.33.255.2
