Conguring Tunnel Allow-Remote Decapsulation
You can congure an IPv4 or IPV6 address or prex whose tunneled packet is accepted for decapsulation.
If you do not congure allow-remote entries, tunneled packets from any remote peer address are accepted.
You can congure up to eight allow-remote entries on any particular multipoint receive-only tunnel.
The following sample conguration shows how to congure a tunnel allow-remote address.
Dell(conf)#interface tunnel 1
Dell(conf-if-tu-1)#ipv6 address 1abd::1/64
Dell(conf-if-tu-1)#ip address 1.1.1.1/24

Conguring Tunnel source anylocal Decapsulation
The tunnel source anylocal command allows a multipoint receive-only tunnel to decapsulate tunnel packets addressed to
any IPv4 or IPv6 (depending on the tunnel mode) address congured on the switch that is operationally UP.
The source anylocal parameters can be used for packet decapsulation instead of the ip address or interface (tunnel
allow-remote command), but only on multipoint receive-only mode tunnels.
The following sample conguration shows how to use the tunnel source anylocal command.
Dell(conf)#interface tunnel 1
Dell(conf-if-tu-1)#ipv6 address 1abd::1/64
Dell(conf-if-tu-1)#ip address 1.1.1.1/24
