2个interface是这样的,用的是public IP
interface FastEthernet0/0
description **** MPLS data interface *****
ip address 10.99.32.1 255.255.255.128
ip pim sparse-dense-mode
duplex full
speed 100
!
interface FastEthernet0/1
description **** Voice interface *****
ip address 10.99.33.1 255.255.255.128
ip pim sparse-dense-mode
duplex full
speed 100
WAN IP,multilink出去。
interface Multilink1
ip address 65.112.128.118 255.255.255.252
ppp multilink
ppp multilink fragment disable
ppp multilink group 1
然后这2个fa又eBGP到remote。
router bgp 65010
neighbor 10.99.30.2 remote-as 65499
neighbor 10.99.30.2 update-source FastEthernet0/0
neighbor 10.99.33.2 remote-as 64699
neighbor 10.99.33.2 update-source FastEthernet0/1
我的问题是这2个FA到底是怎么连的?既然WAN已经有multilink了,而且还建了tunnels
,用iBGP,那么这个eBGP怎么回事呢?
问同事,他们说这2个FA是internal的,但是为啥internal的要eBGP出去?想不通啊。 |

connected to your MPLS-VPN service provider, you are running eBGP as PE-CE
routing protocol. You iBGP session over IPsec/GRE tunnel is for redundancy. |
x*********n 发帖数: 28013 | 3 大哥,我还有一点不明白,物理上接SP的不是serial interface么?然后multilink
virtually combine them together,那么这two Fast Ethernet interfaces也是同时
接SP么?物理上的?
