NETGEAR 8800 Chassis Switch CLI Manual Usage Guidelines Note: This command is not generally supported, and is not recommended for general use. However, to inter-operate with Cisco routers for BGP graceful restart, you must enable the IPv4 unicast address capability. After the capabilities have been enabled, the BGP neighbor announces its capabilities to neighbors in an OPEN message. If IPv4 unicast, IPv4 multicast, or both capabilities are enabled, MBGP extension is enabled and the routes from the specified address families are updated, accepted, and installed. (Thus to enable MBGP, you must configure at least one or both address family capabilities). When both IPv4 unicast and IPv4 multicast are disabled, MBGP is disabled and BGP peering defaults to its backward-compatible behavior of carrying IPv4 unicast updates. In this configuration, the BGP peers accept and install IPv4 unicast routes. Example The following command enables the route-refresh feature for all neighbors: enable bgp neighbor all capability route-refresh enable bgp neighbor originate-default enable bgp [{neighbor} | neighbor all] {address-family [ipv4-unicast | ipv4-multicast]} originate-default {policy } Description Enables the origination and advertisement of a default route to a single BGP neighbor or to all BGP neighbors. Syntax Description neighbor remoteaddr neighbor all ipv4-unicast ipv4-multicast policy-name Specifies the IP address of a BGP neighbor for which the default route is originated and advertised. Specifies that default routes are to be originated and advertised for all BGP neighbors. Specifies that the default routes apply to IPv4 unicast routes. If you do not specify an address family, the command applies to IPv4 unicast routes. Specifies that the default routes apply to IPv4 multicast routes. Specifies a policy to be applied to the default route origination. 1144 | Chapter 25. BGP Commands
