Configuring Tunnel allow-remote Decapsulation

You can configure an IPv4 or IPV6 address or prefix whose tunneled packet will be accepted for decapsulation.
• If no allow-remote entries are configured, then tunneled packets from any remote peer address will be accepted.
• Upto eight allow-remote entries can be configured on any particular multipoint receive-only tunnel.
The following sample configuration shows how to configure 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
Dell(conf-if-tu-1)#tunnel source 40.1.1.1
Dell(conf-if-tu-1)#tunnel mode ipip decapsulate-any
Dell(conf-if-tu-1)#tunnel allow-remote 40.1.1.2
Dell(conf-if-tu-1)#no shutdown
Dell(conf-if-tu-1)#show config
!
interface Tunnel 1
ip address 1.1.1.1/24
ipv6 address 1abd::1/64
tunnel source 40.1.1.1
tunnel allow-remote 40.1.1.2
tunnel mode ipip decapsulate-any
no shutdown

Configuring 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 configured 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 configuration 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
Dell(conf-if-tu-1)#tunnel source anylocal
Dell(conf-if-tu-1)#tunnel mode ipip decapsulate-any
Dell(conf-if-tu-1)#tunnel allow-remote 40.1.1.2
Dell(conf-if-tu-1)#no shutdown
Dell(conf-if-tu-1)#show config
