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 [summary-only] [as-set]

no aggregate-address [summary-only] [as-set]

Function: Configure the aggregate-address. The “no aggregate-address

[summary-only] [as-set]” command deletes the aggregate-address.

Parameter: : IP address, length of mask.

[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
