Hi,
I have 2 routers, R1 and R2.
They are connected through S 0,
R1(s0)----(s0)R2,
lo 0 on R1: 1.1.1.1/24
lo 1 on R1: 11.1.1.1/24
lo 2 on R2: 111.1.1.1/24
R1 in AS 100, R2 in AS 200,
On R1,
router bgp 100
no synchronization
bgp log-neighbor-changes
network 1.1.1.0 mask 255.255.255.0
network 11.1.1.0 mask 255.255.255.0
network 111.1.1.0 mask 255.255.255.0
neighbor 192.168.2.2 remote-as 200
neighbor 192.168.2.2 advertise-map MAP1 non-exist-map
MAP2
no auto-summary
!
ip prefix-list TEST1 seq 5 permit 1.1.1.0/24
!
ip prefix-list TEST2 seq 5 permit 11.1.1.0/24
!
route-map MAP1 permit 10
match ip address prefix-list TEST1
!
route-map MAP2 permit 10
match ip address prefix-list TEST2
If lo 1 on R1 is up, I can see 11.1.1.0/24 and
111.1.1.0/24 on R2, that's what I expect.
Then I shutdown lo 1 on R1, and clear ip bgp * on R1,
But I can only see 111.1.1.0/24, and when I try:
sh ip bgp 1.1.1.0/24
I got:
R1#sh ip bgp 1.1.1.0/24
BGP routing table entry for 1.1.1.0/24, version 2
Paths: (1 available, best #1, table
Default-IP-Routing-Table)
Flag: 0x208
Not advertised to any peer
Local
0.0.0.0 from 0.0.0.0 (111.1.1.1)
Origin IGP, metric 0, localpref 100, weight
32768, valid, sourced, local,
best
I don't why I can not advertise 1.1.1.0/24 to R2. I'm
using 2 2520 with IOS 12.2(1d), does anyone know what
is the problem?
Thanks.
