Usage Information
Enabling tunnel keepalive causes ICMP echo packets to be sent to the keepalive target. The ICMP echo will
be sourced from the tunnel interface logical IPv4 or IPv6 address and will be tunnel encapsulated. The
response will be accepted whether it returns tunnel encapsulated or not.
When conguring tunnel keepalive at both end points of a tunnel interface it is recommended to set the
tunnel keepalive target to the logical IPv4 or IPv6 address of the far end tunnel peer, rather than to the
tunnel destination. This reduces the chance of both ends of the tunnel staying in keepalive down state. If
both ends get into a keepalive down state that does not clear in a few seconds, then performing shutdown -
no shutdown sequence on one end should bring both ends back to up.
tunnel allow-remote
Congure an IPv4 or IPv6 address or prex whose tunneled packets are accepted for decapsulation. If you do not congure allow-
remote entries, tunneled packets from any remote peer address is accepted.
This feature is supported on Dell Networking OS.
Syntax
tunnel allow-remote {ip-address | ipv6-address} [mask]
To delete a congured allow-remote entry use the no tunnel allow-remote command. Any specied
address/mask values must match an existing entry for the delete to succeed. If the address and mask are
not specied, this command deletes all allow-remote entries.
Parameters
ip-address Enter the source IPv4 address in A.B.C.D format.
