Chenyan,

I presume you are working on a scenario that requires you to change the AD
from 200 to 20. Probably the routes learned between the IBGP peer routers
are showing up in your routing table as OSPF or EIGRP routes because they
have a better AD than IBGP (200), and your scenario wants you to learn them
via BGP.

In that case, use the "neighbor X.X.X.X backdoor" statement. Using
"backdoor" on both routers will introduce some difficult problems (i.e., not
sharing routes with other BGP routers, so suddenly routes behind one or both
of these routers are not reachable from other parts of the network). This
is a very hard problem and is worth spending a lot of time practicing.

Good luck. Kym
