EIGRP to BGPAS 1 and AS2 distribution or routing issue.

CiscoPurpleBelt

Level 6

See attachment - looking for some help.

 

All routers in EIGRP can only ping up to the interfaces marked with a red line, and all BGP routers can ping every router except past the BGP interface on R5.

R5 is where BGP65000 (which has 4 routers as you can see in BGP65000) is redistributed into EIGRP100, and R5 can ping everything in the topology.

R7 joins EIGRP100 and 200. As I stated there are no comms issues with EIGRP routers except going past the interaces marked with a red wall/line.

R11 is a Route-Reflector. See applicable configs for R11, R5, and R6 since the issue seems to pertain to either my RR configs on R11, or distribution configs on R5. No static routes/GWs, ACLs, route-maps, filters, etc. are configured.

 

R11#sh running-config | section router
router bgp 65000

See anything that stands out or may be incorrect?

Added the "bgp redistribute-internal" config under bgp 65000 on R5 and vioala!

Looks like BGP would not share iBGP routes with EIGRP (IGP) without this command.
