Example For Configuring Inter-Provider Vpn Option A - 3Com MSR 50 Series Configuration Manual

Example for Configuring
Inter-Provider VPN
Option A
127.0.0.0/8
127.0.0.1/32
The following takes PE 1 as an example:
[PE1] display ip routing-table
Routing Tables: Public
Destinations : 11
Destination/Mask
1.1.1.9/32
2.2.2.9/32
10.2.1.0/24
20.1.1.0/24
20.1.1.1/32
127.0.0.0/8
127.0.0.1/32
172.1.1.0/24
172.1.1.1/32
172.1.1.2/32
172.2.1.0/24
[PE1] display ip routing-table vpn-instance vpn1
Routing Tables: vpn1
Destinations : 3
Destination/Mask
10.1.1.0/24
10.1.1.2/32
10.2.1.0/24
The CEs should be able to ping each other.
[CE1] ping 10.2.1.1
PING 10.2.1.1: 56
Reply from 10.2.1.1: bytes=56 Sequence=1 ttl=253 time=41 ms

Reply from 10.2.1.1: bytes=56 Sequence=4 ttl=253 time=68 ms
Reply from 10.2.1.1: bytes=56 Sequence=5 ttl=253 time=67 ms
--- 10.2.1.1 ping statistics ---
5 packet(s) transmitted
5 packet(s) received
0.00% packet loss
round-trip min/avg/max = 41/62/69 ms
Network requirements
CE 1 and CE 2 belong to the same VPN. CE 1 accesses the network through PE
■
1 in AS 100 and CE 2 accesses the network through PE 2 in AS 200.
Inter-provider MPLS L3VPN is implemented using option A. That is, the
■
VRF-to-VRF method is used to manage VPN routes.
The MPLS backbone in each AS runs OSPF.
