It can be used with an interface, an IP address or an access-list. When used with an IP address, the peer is a remote PE loopback. When used with an IP address, the peer is the IGP next hop. There must be an LSP destined to the IP address used. There must be a TE-Tunnel LSP destined to the IP address used.
