Configuring Multiprotocol Bgp Pe To Pe Routing Sessions - Cisco 10000-2P2-2DC Software Configuration Manual

Configuration Tasks for RA to MPLS VPN
Command
Step 4
Router(config)# interface virtual-template
number
Step 5
Router(config-if)# ip vrf forwarding
vrf-name
Apply the ip vrf forwarding command and then the ip address command. If you do not, the ip vrf
Note
forwarding command removes the existing IP address on the interface.
Example 3-1
interface GigabitEthernet7/0/0.1
encapsulation dot1Q 11
ip vrf forwarding vpn1
ip address 192.168.1.1 255.255.255.0
!
Example 3-2
interface Virtual-Template1
ip vrf forwarding vpn1
ip unnumbered Loopback1
no peer default ip address
ppp authentication chap vpn1
ppp authorization vpn1
ppp accounting vpn1

Configuring Multiprotocol BGP PE to PE Routing Sessions

To configure multiprotocol BGP (MP-BGP) routing sessions between the PE routers, enter the following
commands on the PE routers beginning in global configuration mode:
Command
Step 1
Router(config)# router bgp autonomous-system
Step 2
Router(config-router)# no bgp default
ipv4-unicast
Step 3
Router(config-router)# neighbor {ip-address |
peer-group-name} remote-as as-number
Step 4
Router(config-router)# neighbor {ip-address |
peer-group-name} update-source interface-type
Step 5
Router(config-router)# neighbor {ip-address |
peer-group-name} activate

Purpose
Creates a virtual template interface and enters interface
configuration mode.
Associates a VRF with a virtual template interface.

Associating a VRF with a Virtual Template Interface
Chapter 3
Purpose
Configures the internal BGP (iBGP) routing process with the
autonomous system number passed along to other
iBGP routers.
Disables IPv4 BGP routing.
Configures the neighboring PE router's IP address or iBGP
peer group and identifies it to the local autonomous system.
The MP-BGP neighbors must use the loopback addresses.
Allows iBGP sessions to use any operational interface for
TCP connections.
Activates route exchanges with the global BGP neighbors.
