Configuring Vpn Route Targets - Cisco CRS Series Configuration Manual

Configuring MVPN Extranet Routing

Configuring VPN Route Targets

This procedure demonstrates how to configure a VPN route target for each topology.
Route targets should be configured so that the receiver VRF has unicast reachability to prefixes in the
Note
source VRF. These configuration steps can be skipped if prefixes in the source VRF are already imported
to the receiver VRF.
SUMMARY STEPS
1. configure
2. vrf source-vrf
3. address-family [ipv4 | ipv6} unicast
4. import route-target [xx.yy:nn | as-number:nn | ip-address:nn]
5. export route-target [xx.yy:nn | as-number:nn | ip-address:nn]
6. commit
7. configure
8. vrf receiver-vrf
9. Repeat Step 3 through Step 6.
DETAILED STEPS
Command or Action
Step 1
configure
Step 2 vrf source-vrf
Example:
RP/0/RP0/CPU0:router(config)# vrf green
RP/0/RP0/CPU0:router(config-vrf)#
Step 3 address-family [ipv4 | ipv6} unicast
Example:
RP/0/RP0/CPU0:router(config-vrf)#
address-family ipv4 unicast
Step 4
import route-target [xx.yy:nn | as-number:nn |
ip-address:nn]
Example:
RP/0/RP0/CPU0:router(config-vrf-af)# import
route-target 234:222
RP/0/RP0/CPU0:router(config-vrf-af)# import

Implementing Multicast Routing on Cisco IOS XR Software
Purpose
Configures a VRF instance for the source PE router.
Specifies a unicast IPv4 or IPv6 address family and enters
address family configuration submode.
Note Only IPv4 addressing is supported for
extranet.
Imports the selected route target, optionally expressed as one
of the following :
• 4-byte AS number of the route target in xx.yy:nn format.
Range is 0-65535.0-65535:0-65535
• AS number of the route target in nn format. Range is
0-65535.
