Chapter 41 Configuring VRF-lite
EBGPv6
To configure EBGPv6, do the following:
Command
Switch> enable
Step 1
Switch# configure terminal
Step 2
Switch(config)# router bgp as-number
Step 3
Switch(config-router)# neighbor
Step 4
peer-group-name peer-group
Switch(config-router)# neighbor
Step 5
{ip-address | ipv6-address[%] |
peer-group-name}remote-as
autonomous-system-number
[alternate-as
autonomous-system-number ...]
Switch(config-router)#
Step 6
address-family ipv6 [vrf vrf-name]
[unicast | multicast | vpnv6]
Switch(config-router-af)# neighbor
Step 7
ipv6-address peer-group
peer-group-name
Switch(config-router-af)# neighbor
Step 8
{ip-address | peer-group-name |
ipv6-address[%]}route-map map-name
{in | out}
Switch(config-router-af)# exit
Step 9
This example shows how to configure EBRPv6:
Switch(config)# router bgp 2
Switch(config-router)# bgp router-id 2.2.2.2
Switch(config-router)# bgp log-neighbor-changes
Switch(config-router)# no bgp default ipv4-unicast
Switch(config-router)# neighbor 2500::1 remote-as 1
Switch(config-router)# neighbor 4000::2 remote-as 3
Switch(config-router)# address-family ipv6 vrf b1
Switch(config-router-af)# network 2500::/64
Switch(config-router-af)# network 4000::/64
Switch(config-router-af)# neighbor 2500::1 remote-as 1
Switch(config-router-af)# neighbor 2500::1 activate
Switch(config-router-af)# neighbor 4000::2 remote-as 3

Purpose
Enters privileged EXEC mode.
Enter your password if prompted.
Enters global configuration mode.
Enters router configuration mode for the specified routing
process.
Creates a multiprotocol BGP peer group.
Adds the IPv6 address of the neighbor in the specified
autonomous system to the IPv6 multiprotocol BGP
neighbor table of the local router.
Specifies the IPv6 address family, and enters address
family configuration mode.
The unicast keyword specifies the IPv6 unicast
•
address family. By default, the switch is placed in
configuration mode for the IPv6 unicast address
family if theunicast keyword is not specified with the
address-family ipv6command.
The multicast keyword specifies IPv6 multicast
•
address prefixes.
Assigns the IPv6 address of a BGP neighbor to a peer
group.
Applies a route map to incoming or outgoing routes.
Changes to the route map will not take effect for
•
existing peers until the peering is reset or a soft reset
is performed. Using the clear bgp ipv6 command with
the soft and in keywords will perform a soft reset.
Exits address familyconfiguration mode, and returns the
router to router configuration mode.
