address. This route is typically used when the MultiVoice Gateway is trying to locate a server
on a client machine to handle challenges for a token security card.
Adding an IP route
To add to the MultiVoice Gateway unit’s routing table a static route that will be lost when the
unit resets, enter the IProute Add command in the following format:
iproute add destination gateway [metric]
where destination is the destination network address, gateway is the IP address of the
router that can forward packets to that network, and
metric is the virtual hop count (default
8) to the destination network. For example:
ascend% iproute add 10.1.2.0 10.0.0.3/24 1
This sample command adds a route to the 10.1.2.0 network and all of its subnets. The new
route is through the IP router located at 10.0.0.3/24. The metric to the route is 1 (it is one hop
away).
If you try to add a route to a destination that already exists in the routing table, the MultiVoice
Gateway replaces the existing route, but only if it has a higher metric than the new route. If you
get the message Warning: a better route appears to exist, the MultiVoice
Gateway has rejected your attempt to add a route because the routing table already contained
the same route with a lower metric. Note that RIP updates can change the metric for the route.
Deleting an IP route
To remove a route from the MultiVoice Gateway unit’s routing table, enter the IProute Delete
command in the following format:
iproute delete destination gateway
For example:
iproute delete 10.1.2.0 10.0.0.3/24
Note: RIP updates can add back any route you remove with IProute Delete. Also, the
MultiVoice Gateway restores all routes listed in the Static Route profile after a system reset.
Displaying route statistics
The Traceroute command is useful for locating slow routers or diagnosing IP routing
problems. It traces the route an IP packet follows, by launching UDP probe packets with a low
Time-To-Live (TTL) value and then listening for an ICMP time exceeded reply from a router.
The Traceroute command uses the following syntax:
traceroute [-n] [-v] [-m max_ttl ] [-p port ] [-q nqueries ]
[-w
waittime ] host [ datasize ]
All flags are optional. The only required parameter is the destination host name or IP address.
