Usage Guide:
To support VPN, VRF has to be enabled on the border routers; to realize
VPN, create neighbors for BGP with the VRF address family on the private network, and
with VPNv4 address-family on the public network. Configuration performed with this
command to specific VRF, is independent from IPv4 unicast address-family. The VRF
configuration is performed by using ip vrf <NAME> command under global mode. The
address-family configuration is only available after the VRF RD is set.
Example:
In the example below a VRF name DC1 is created with RD at 100: :10, and
then enter the BGP address-family for its configuration.
Switch(config)#ip vrf DC1
Switch(config-vrf)#rd 100:10
Switch(config-vrf)#exit
Switch(config)#router bgp 100
Switch(config-router)#address-family ipv4 vrf DC1
Switch(config-router-af)#
14.8.3.3 address-family vpnv4
Command: address-family vpnv4
Function:
Enter the BGP VPNv4 address family mode
Parameter:
None
Command Mode:
BGP routing mode
Usage Guide:
To support VPN, VRF has to be enabled on the border routers; to realize
VPN, create neighbors for BGP with the VRF address family on the private network, and
with VPNv4 address-family on the public network. When configuring VPNv4
address-family with this command, IPv4 unicast address connection is available. Its
neighbor configuration could be the same with IPv4 unicast only by using neighbor
A.B.C.D activate on this neighbor to enable this address-family
Example:
Switch(config)#router bgp 100
Switch(config-router)#address-family vpnv4
Switch(config-router-af)#
14.8.3.4 aggregate-address
Command: aggregate-address <ip-address/M> [summary-only] [as-set]
no aggregate-address <ip-address/M> [summary-only] [as-set]
Function:
Configure the aggregate-address.The “
no aggregate-address
<ip-address/M> [summary-only] [as-set]
” command deletes the aggregate-address
Parameter: <ip-address/M>:
IP address, length of mask
[summary-only]
: Send summary only ignoring specific route
