Using Tunnels To Advertise Vpn Routes - HP 3600 v2 series Configuration Manual

# Perform similar configuration on the MCE and PE 1 for VPN 2. Redistribute the OSPF routes of VPN
instance vpn2 into the eBGP routing table. (Details not shown)
The following output shows that PE 1 has learned the private route of VPN 2 through BGP:
[PE1] display ip routing-table vpn-instance vpn2
Routing Tables: vpn2
Destinations : 5

192.168.10.0/24
Now, the MCE has redistributed the OSPF routes of the two VPN instances into the eBGP routing tables
of PE 1.

Using tunnels to advertise VPN routes

Network requirements
As shown in
both are connected to sites of VPN 1 and VPN 2. The sites of VPN 1 use routing protocol OSPF and
reside in the backbone area, that is, area 0. The two sites of VPN 2 use RIP and OSPF, respectively, and
the OSPF area 0 is used.
Configure MCE 1 and MCE 2 to correctly advertise routing information of the two VPNs.

Configuration considerations
As shown in
information of the VPN, you can create a VPN instance for each VPN and bind the VPN instances to
specific interfaces (the tunnel interfaces and interfaces connected to the VPN sites). In this way the current
network is simplified into two separate topologies, as shown in
advertise routes of different VPNs through different paths.
