Keepalive Retries:
The number of times that a keepalive packet will be sent (if no response is received from the
remote end) before the tunnel is declared as being down.
Keepalives activate interfaces:
This specifies whether or not the GRE keepalive packets will activate the tunnel. If set to YES
and the tunnel drops the GRE keepalive packet will try to raise the tunnel again. If set to NO
and the tunnel has been marked as down due to the GRE keepalives not being received, the
router will only raise the tunnel if a packet (other than a GRE keepalive) needs to be routed.
IP analysis:
When set to ON, the un-encapsulated IP traffic will be captured into the analyser trace.
Tunnel analysis:
When set to ON, the GRE encapsulated packets and keepalives will be captured to the analyser
trace.
Firewall:
The Firewall parameter is used to turn Firewall script processing “On” or “Off” for this inter-
face. If using the firewall for problem detection on a tunnel interface, the interface to put OOS
will need to be specified, eg:
pass out break end on tun 0 from any to 100.100.100.29 port=4000
flags S!A inspect-state oos ppp 1 5
IGMP:
This IGMP parameter is used to enable or disable the transmission and reception of IGMP
packets on this interface. IGMP is used to advertise members of multicast groups. If IGMP is
enabled, and a member of a multicast group is discovered on this interface, multicast packets for
this group received on other interfaces will be sent out this interface.
