R2:
interface fastethernet 0/0
ip address 10.6.2.2 255.255.255.0
router ospf 1
network 10.6.2.0 0.0.0.255 area 0
router bgp 1
neighbor 10.6.2.1 remote-as 1
My question is this - Why does network 10.6.1.0/24 not show up in BGP?
Redistributing connected with the route-map on R1 adds an external type 2
entry to the OSPF database, and then BGP is configured to redistribute all
OSPF information (internal and external 1/2). The only way to get the
10.6.1.0/24 network into BGP (without a network command on R1) is to
redistribute OSPF into BGP on R2...Why can R2 perform this redsitribution,
but R1 cannot?
Thanks,
Jack
