The following sample conguration shows how to use the interface tunnel conguration commands.
Dell(conf-if-gi-1/1)#show config

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
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
Conguring the Tunnel Source Anylocal
You can use the anylocal argument in place of the ip address or interface, but only with multipoint receive-only mode tunnels. The tunnel
source anylocal
command allows the 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 following sample conguration shows 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
