Configuring Tunnel Allow-Remote

Decapsulation

You can configure an IPv4 or IPV6 address or prefix whose tunneled packet is accepted for decapsulation.

• If you do not configure allow-remote entries, tunneled packets from any remote peer address are

accepted.

• You can configure up to eight allow-remote entries 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.
