peer redirect ipv6 recursive-lookup tunnel (BGP-IPv6-flow address family view)

Function

The peer redirect ipv6 recursive-lookup tunnel command enables a device to recurse the BGP IPv6 Flow Specification routes received from a peer to a tunnel.

The undo peer redirect ipv6 recursive-lookup tunnel command restores the default configuration.

By default, a device cannot recurse the BGP IPv6 Flow Specification route received from a peer to a tunnel.

Format

peer { ipv4-address | ipv6-address } redirect ipv6 recursive-lookup tunnel tunnel-selector tunnel-selector-name

undo peer { ipv4-address | ipv6-address } redirect ipv6 recursive-lookup tunnel

undo peer { ipv4-address | ipv6-address } redirect ipv6 recursive-lookup tunnel tunnel-selector tunnel-selector-name

Parameters

Parameter	Description	Value
ipv4-address	Specifies the IPv4 address of a BGP peer.	The value is in dotted decimal notation.
ipv6-address	Specifies the IPv6 address of a BGP peer.	The value is in the format of X:X:X:X:X:X:X:X.
tunnel-selector tunnel-selector-name	Specifies the name of a tunnel policy selector.	The value is a string of 1 to 40 case-sensitive characters, spaces not supported. The string can contain spaces if it is enclosed with double quotation marks (").

Usage Guidelines

Usage Scenario

In a dynamic BGP IPv6 Flow Specification scenario, to trigger recursion to a tunnel, run the peer redirect ipv6 recursive-lookup tunnel command.
