Configuring the Tunnel allow-remote
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 tunnel allow-remote 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 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 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 configured on the switch that is operationally UP.
The following sample configuration 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
