Usage Information
You can congure up to eight allow-remote entries on any multipoint receive-only tunnel.
This command fails 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 you congure any allow-remote , the tunnel source or tunnel mode commands fail if the outer header
address family does not match that of the congured allow-remote.

(IPv6) to the tunnel header DSCP (IPv4)/Trac 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)/Trac
