- Add a new node `SRV6_ENCAP_NODE` to the CLI graph. This node allows users to configure encapsulation parameters for SRv6, including the source address of the outer encapsulating IPv6 header. - Install a new CLI command `source-address` under the `SRV6_ENCAP_NODE` node. This command is used to configure the source address of the outer encapsulating IPv6 header. - Install a new CLI command `no source-address` under the `SRV6_ENCAP_NODE` node. This command is used to unset the source address of the outer encapsulating IPv6 header and restore the default source address. Examples: ``` router# segment-routing router(sr)# srv6 router(srv6)# encapsulation router(srv6-encap)# source-address fc00:0:1::1 ``` ``` router# segment-routing router(sr)# srv6 router(srv6)# encapsulation router(srv6-encap)# no source-address ``` Signed-off-by: Carmine Scarpitta <carmine.scarpitta@uniroma2.it>
