Version Description
9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Introduced on the MXL.
Usage
Information
When configured, the system will send ICMP echo probe packets at the configured interval and expect a
response within the configured number of attempts, else the tunnel interface will be declared operational
down.
tunnel allow-remote
Configure an IPv4 or IPv6 address or prefix whose tunneled packets will be accepted for decapsulation. If no allow-remote
entries are configured, tunneled packets from any remote peer address will be accepted.
Syntax tunnel allow-remote {ip-address | ipv6-address} [mask]
Use the no tunnel allow-remote command to delete a configured allow-remote entry. Any specified
address/mask values must match an existing entry for the delete to succeed. If the address and mask are
not specified, this command deletes all allow-remote entries.
Parameters
ip-address Enter the source IPv4 address in A.B.C.D format.
ipv6–address Enter the source IPv6 address in X:X:X:X::X format.
mask (OPTIONAL) Enter a network mask in /prefix format (/x) or A.B.C.D to match a
range of remote addresses. The default mask is /32 for IPv4 addresses and /128
for IPv6 addresses, which match only the specified address.
Defaults If no tunnel allow remote is configured, all traffic which is destined to tunnel source address will be
decapsulated.

Version Description
9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Introduced on the MXL.
Usage
Information
Up to eight allow-remote entries can be configured on any particular multipoint receive-only tunnel.
This command will fail if the address family entered does not match the outer header address family of
the tunnel mode, tunnel source, or any other tunnel allow-remote.
If any allow-remote are configured, the tunnel source or tunnel mode commands will fail if the outer
header address family does not match that of the configured allow-remote.
tunnel dscp
Configure the method to set the DSCP in the outer tunnel header.
Syntax
tunnel dscp {mapped | <value>}
To use the default tunnel mapping behavior, use the no tunnel dscp value command.
Parameters
mapped Enter the keyword mapped to map the original packet DSCP (IPv4)/Traffic Class
(IPv6) to the tunnel header DSCP (IPv4)/Traffic Class (IPv6) depending on the
mode of tunnel.
value Enter a value to set the DSCP value in the tunnel header. The range is from 0 to
63. The default value of 0 denotes mapping of original packet DSCP (IPv4)/Traffic
