Configuring Tunnel Allow-Remote Decapsulation; Configuring Tunnel Source Anylocal Decapsulation - Dell Z9500 Configuration Manual

The following sample configuration shows how to use the interface tunnel configuration commands.
Dell(conf-if-te-1/1)#show config
!
interface TenGigabitEthernet 1/1
ip address 20.1.1.1/24
ipv6 address 20:1::1/64
no shutdown
Dell(conf)#interface tunnel 1
Dell(conf-if-tu-1)#ip unnumbered tengigabitethernet 1/1
Dell(conf-if-tu-1)#ipv6 unnumbered tengigabitethernet 1/1
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)#no shutdown
Dell(conf-if-tu-1)#show config
!

tunnel source 40.1.1.1
tunnel mode ipip decapsulate-any
no shutdown
Dell(conf-if-tu-1)#

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.
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
