BGP issue has me stumped
Testing some different configuration options I decided to test an eBGP peering between R8 and R10, from CCIE v5 INE topology. On both routers, R8 BGP AS 200 and R10 BGP AS 54 per the workbook topology. Using OSPF on Routers 1-8.
neighbor 22.214.171.124 remote-as 200
neighbor 126.96.36.199 disable-connected-check
neighbor 188.8.131.52 update-source Loopback0
neighbor 184.108.40.206 remote-as 54
neighbor 220.127.116.11 disable-connected-check
neighbor 18.104.22.168 update-source Loopback0
Straightforward and simple, added a static route /32 on each router pointing to the peers loopback.
ip route 22.214.171.124 255.255.255.255 126.96.36.199
ip route 188.8.131.52 255.255.255.255 184.108.40.206
I now have static routes in the IP routing table and the peering comes up as expected. All seemed well until I started the Route Relector section, following Brian's video, RR in the dataplane, R5 as the RR and out of the data plane on R2 as the RR. From R10 I couldn't trace to the 220.127.116.11/24 network, it died at R8. Ok Let's try the reverse path, traced to 18.104.22.168 from R3, dies at R8. Common denominator, R8 right? After some thought I advertised the connected 22.214.171.124/24 into BGP on R8 and now I can successfully trace to R3's .37 network from R10. Now for the reverse path, this is where I can't seem to figure out. I trace from R3 to R10 and die at R8, I then, just to see if it would work, advertised the .108 network into BGP. No dice, still die at R8. Mind you, after every modification I do a full clear of bgp both soft in/out and hard just see the differences (clear ip bgp * out/in). No dice, I checked the routing table,
I have a static host route on R8:S 126.96.36.199 [1/0] via 188.8.131.52,
also checked the CEF table: 184.108.40.206/32 nexthop 220.127.116.11 GigabitEthernet1.108
Still nothing, R3's info: Sho ip bgp *>i 18.104.22.168/32 22.214.171.124 0 100 0 ?
The CEF table on R3 126.96.36.199/32 nexthop 169.254.100.5 GigabitEthernet1.100
Type escape sequence to abort.
