Hi, I am working from a book and trying to follow along by creating the
scenarios. I have a problem with this simple BGP set up from what the
book is telling me I should see when doing sh ip bgp and what I actually
do see. Here's the topology etc. (I hope it come out looking right). Any
ideas?
Thanks,
Steve

The book says I should see this in the BGP table on R3.
Rack3R3#sh ip bgp
BGP table version is 2, local router ID is 192.1.2.1
Status codes: s suppressed, d damped, h history, * valid, > best, i -
internal
Origin codes: i - IGP, e - EGP, ? - incomplete

*>i131.2.2.0/24 131.2.2.2 0 100 0 I
Rack3R3#
Instead I see this.
Rack3R3#sh ip bgp
BGP table version is 2, local router ID is 192.1.2.1
Status codes: s suppressed, d damped, h history, * valid, > best, i -

Rack3R3#
Did I do something wrong? I'm running IOS 12.2(16)
