Example For Configuring Inter-Provider Vpn Option B - 3Com S7906E Configuration Manual

# Configure PE 2.
[PE2] bgp 200
[PE2-bgp] peer 3.3.3.9 as-number 200
[PE2-bgp] peer 3.3.3.9 connect-interface loopback 0
[PE2-bgp] ipv4-family vpnv4
[PE2-bgp-af-vpnv4] peer 3.3.3.9 enable
[PE2-bgp-af-vpnv4] peer 3.3.3.9 next-hop-local
[PE2-bgp-af-vpnv4] quit
[PE2-bgp] quit
6) Verify your configurations
After you complete the above configurations, the CEs should be able to learn the interface routes from
each other and ping each other.

Example for Configuring Inter-Provider VPN Option B

Network requirements
Site 1 and Site 2 belong to the same VPN. CE 1 of Site 1 accesses the network through PE 1 in AS
100 and CE 2 of Site 2 accesses the network through PE 2 in AS 600.
PEs in the same AS runs IS-IS between them.
PE 1 and ASBR-PE 1 exchange labeled IPv4 routes by MP-IBGP.
PE 2 and ASBR-PE 2 exchange labeled IPv4 routes by MP-IBGP.
ASBR-PE 1 and ASBR-PE 2 exchange labeled IPv4 routes by MP-EBGP.
ASBRs do not perform VPN target filtering of received VPN-IPv4 routes.
