Conguring Tunnel Allow-Remote Decapsulation
You can congure an IPv4 or IPV6 address or prex whose tunneled packet is accepted for decapsulation.
• If you do not congure allow-remote entries, tunneled packets from any remote peer address are accepted.
• You can congure up to eight allow-remote entries on any particular multipoint receive-only tunnel.
The following sample conguration shows how to congure 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

Conguring 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 congured 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 conguration 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
