Allied Telesis VERSION 5.4.3-2.6 manual Bgp default ipv4-unicast BGP and BGP4+

BGP and BGP4+ Commands

Usage [BGP/BGP4+]	Route dampening minimizes the instability caused by route flapping. A penalty is added
	for every flap in a flapping route. As soon as the total penalty reaches the suppress limit
	the advertisement of the route is suppressed. This penalty is decayed according to the
	configured half time value. Once the penalty is lower than the reuse limit, the route
	advertisement is un-suppressed.
	The dampening information is purged from the router once the penalty becomes less
	than half of the reuse limit.
Example
[BGP]	awplus#	configure terminal
	awplus(config)#	router bgp 11
	awplus(config-router)#bgp dampening 20 800 2500 80 25
Example
[BGP4+]	awplus#	configure terminal
	awplus(config)#	router bgp 11
	awplus(config-router)# address-family ipv6
	awplus(config-router-af)#	bgp dampening 20 800 2500 80 25

bgp default ipv4-unicast (BGP and BGP4+)

This command configures BGP defaults and activates IPv4-unicast for a peer by default. This affects BGP global configuration. By default, BGP exchanges IPv4 prefixes with a peer.

The no variant of this command disables this function. The BGP routing process will no longer exchange IPv4 addressing information with BGP neighbor routers. Note that disabling the exchange of IPv4 prefixes will also enable an IPv6 only BGP4+ network.

Syntax bgp default ipv4-unicast

no bgp default ipv4-unicast

Default This is enabled by default.

Mode Router Configuration

Usage Use the negated form of this command to enable an IPv6 only BGP4+ network.

Examples

awplus#	configure terminal
awplus(config)#	router	bgp 100
awplus(config-router)#	bgp default ipv4-unicast
awplus#	configure terminal
awplus(config)#	router	bgp 100
awplus(config-router)#	no bgp	default ipv4-unicast
