Chapter 32 IPv6 Support on the Cisco ASR 901 Router

How to Configure IPv6 Support on the Cisco ASR 901 Router

	Command or Action	Purpose
Step 3
	ipv6 route static bfd [vrf vrf-name]	Specifies static route IPv6 BFDv6 neighbors.
	interface-ype interface-number ipv6-address	• vrf-name—(Optional) Name of the virtual routing and
	[unassociated]
		forwarding (VRF) instance by which static routes are
	Example:	specified.
		• interface-type—Interface type.
	Router(config)# ipv6 route static bfd vlan 4000
	2001::1	• interface-number—SVI name.
		• ipv6-address—IPv6 address of the neighbor.
		• unassociated—(Optional) Moves a static BFD
		neighbor from associated mode to unassociated mode.
Step 4
	ipv6 route [vrf vrf-name]	Establishes static IPv6 routes.
	ipv6-prefix/prefix-length {ipv6-address	• vrf-name—(Optional) Name of the virtual routing and
	interface-type [interface-number ipv6-address]}
	[nexthop-vrf [vrf-name1default]]	forwarding (VRF) instance by which static routes are
	[administrative-distance]	specified.
	[administrative-multicast-distance unicast	• ipv6-prefix—The IPv6 network that is the destination of
	multicast] [next-hop-address] [tag tag]
		the static route. Can also be a host name when static
	Example:	host routes are configured.
		• ipv6-address—The IPv6 address of the next hop that
	Router(config)# ipv6 route 2001:DB8::/64 vlan
	4000 2001::1	can be used to reach the specified network.
		• interface-type—Interface type.
		• interface-number—SVI name.
		• nexthop-vrf—(Optional) Indicator that the next hop is
		a VRF.
		• vrf-name1—(Optional) Name of the next-hop VRF.
		• default—(Optional) Indicator that the next hop is the
		default.
		• administrative-distance—(Optional) An administrative
		distance. The default value is 1, which gives static
		routes precedence over any other type of route except
		connected routes.
		• administrative-multicast-distance—(Optional) The
		distance used when selecting this route for multicast
		Reverse Path Forwarding (RPF).
		• unicast—(Optional) Specifies a route that must not be
		used in multicast RPF selection.
		• multicast—(Optional) Specifies a route that must not
		be populated in the unicast Routing Information Base
		(RIB).
		• next-hop-address—(Optional) Address of the next hop
		that can be used to reach the specified network.
		• tag tag—(Optional) Tag value that is used as a “match”
		value for controlling redistribution via route maps.
