Conguring the Tunnel allow-remote
You can congure an IPv4 or IPV6 address or prex whose tunneled packet will be accepted for decapsulation.
.
• If no allow-remote entries are congured, then tunneled packets from any remote peer address will be accepted.
• Upto eight allow-remote entries can be congured on any particular multipoint receive-only tunnel.
The following sample conguration 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

Conguring the tunnel source anylocal
The anylocal argument can be used in place of the ip address or interface, but only with multipoint receive-only mode tunnels. The
tunnel source anylocal command will allow the multipoint receive-only tunnel to decapsulate tunnel packets addressed to any IPv4 or
IPv6 (depending on the tunnel mode) address congured on the switch that is operationally UP.
The following sample conguration shows 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
