BGP问题求助

这是试验top,想试试r1 pin小g 通r3 但没有成功. 以下是3个路由器的配置,请那位大师指点一下, 谢谢.

R1:
interface Loopback0
ip address 10.10.10.10 255.255.255.0
!
!
interface Serial1/0
ip address 172.8.12.1 255.255.255.0
serial restart-delay 0
clock rate 64000

router eigrp 1
network 10.10.10.0 0.0.0.255
network 172.8.12.0 0.0.0.255
no auto-summary
!
router bgp 12
no synchronization
bgp router-id 10.10.10.10
bgp log-neighbor-changes
neighbor 20.20.20.20 remote-as 12
neighbor 20.20.20.20 **-source Loopback0
no auto-summary
!




R2:

interface Loopback0
ip address 20.20.20.20 255.255.255.0
!

interface Serial1/0
ip address 172.8.12.2 255.255.255.0
serial restart-delay 0
!
interface Serial1/1
ip address 172.8.23.2 255.255.255.0
serial restart-delay 0
!

router eigrp 1
network 20.20.20.0 0.0.0.255
network 172.8.12.0 0.0.0.255
network 172.8.23.0 0.0.0.255
no auto-summary
!
router bgp 12
no synchronization
bgp router-id 20.20.20.20
bgp log-neighbor-changes
neighbor 10.10.10.10 remote-as 12
neighbor 10.10.10.10 **-source Loopback0
neighbor 10.10.10.10 next-hop-self
neighbor 172.8.23.3 remote-as 3
no auto-summary




R3:

interface Loopback0
ip address 30.30.30.30 255.255.255.0


interface Serial1/0
ip address 172.8.23.3 255.255.255.0
serial restart-delay 0


router bgp 3
no synchronization
bgp router-id 30.30.30.30
bgp log-neighbor-changes
network 30.30.30.0 mask 255.255.255.0
network 172.8.23.0 mask 255.255.255.0
neighbor 172.8.23.2 remote-as 12
no auto-summary
!


目前只能在每个路由器上看到IBGP与EBGP邻居关系都已经建立,但是无法从r1ping到r3.

R3没有回程路由

-sweat-已经发现问题所在了 谢谢...

ping不通，先看路由，在看策略。BGP有时候还有路由黑洞

IGP通了，再搞BGP

回复速度神了~

R3没有任何回R1路由条目，你可以再两边的BGP里面宣告网络
