35.3 address-family vpnv4
Command: address-family vpnv4
Function: Enter the BGP VPNv4 address family mode.
Parameter: None.
Command Mode: BGP route 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)#
35.4 aggregate-address
Command: aggregate-address
no aggregate-address
Function: Configure the aggregate-address. The “no aggregate-address
[summary-only] [as-set]” command deletes the aggregate-address.
Parameter:
[summary-only]: Send summary only ignoring specific route.
[as-set]: Show AS on the path in list, each AS is shown once.
Default: No aggregate configuration.
Command Mode: BGP route mode
Usage Guide: Address aggregation reduces spreading routing messages outside. Use summary-only
option so to spread aggregate route to the neighbors without spreading specific route. as-set option will
list AS from each route covered by the aggregation only once without repeat.
Example:
Switch(config-router)#aggregate-address 100.1.0.0/16 summary-only
Switch(config-router)#aggregate-address 100.2.0.0/16 summary-only as-set
