route metric to T1 = 999 ?????????

[pbxphoneman]

I have a point to point T1 hooked up to a small network that will connect a remote computer to my LAN...which has the DSL internet on it.when I hooked up the T1 router to my LAN..I have a rout metric that showed up ( ROUTE PRINT)of 999
Active Routes:
network address = 0.0.0.0
netmask = 0.0.0.0
gateway address = 192.168.254.100 (my t1 router ip)
interface =192.168.254.12 (this computer)
metric = 999

plus other entries..but everything else looks in order..metrics =1 or 2
Question?????
where did this metric of 999 come from?
I never assigned any metric to any route other then the static one in my router for for 192.168.3.1 (metric 2) and that was the subnet route between the 2 LANS for the T1 router.which doesn't show up on the route command (it shouldn't anyway)
when I boot the computer without the T1 router plugged in (ethernet) it doesn't show up.
I haven't any WIN's,DNS,Hosts or LMHOSTS running that even has this IP listed in it.
maybe this is common?
The ping times to the router are fine..but i was just curious why so high a metric.
thanks for any input !!!

Hmmm. Are you running DHCP? On our corporate network, our DHCP server gives my machine a primary and a backup default gateway. The primary has a metric of 1 and the secondary a metric of 2. If you've statically configured the machines IP and DG, there metric can be set in a Windows machine. On my W2k Pro box, I go to the properties of my network connection, to properties of TCP/IP, and then to advanced settings. You'll see where you can manually set the metric for your DG.

My dsl router/hub that everything is connected to ,does DHCP.The rest of the win98 machines receive the addys from that router.The T1 router has a static IP that is out of the scope of the DHCP though.
I was curious to find out if routers broadcast there static IP's out to machines and place "themselves" in the ROUTE of that machine when they come up on the LAN.I don't have anything on this machine that points to that router yet in the TCP/IP properties of my NIC.

thanks for your input!!

There was some tinkering around with router discovery protocols that would do what you mentioned a while back but none came into popular use. Routers do send out stuff, such as Cisco Discovery Protocol, that identify their capabilities. But that was intended for Cisco-Cisco communications, not Cisco-host communications, so I doubt that's it (besides, CDP doesn't have anything to do with metrics). I guess I don't know enough about Win98 to answer you question definitively. In general, the gateway has to be statically entered into the host or the DHCP server must announce the gateway. A sniffer would probably help, but wouldn't necessarily identify which traffic the router was sending that the host appears to be picking up on. Perhaps it's overhearing ARPs, or something along those lines and just assigning a default metric? I also know that some routers send out "gratuitous ARPs" to announce their presence to other routers, but I haven't seen that happen on a real network in a while. Again, an ARP wouldn't inlcude a metric, so it would have to be that the Win98 box was coming up with that all on its own.

Hope someone knows for sure....

I think i found a setting in my T1 router (ICMP router discovery)enable & disable.I turned it off and low and behold I finally got rid of the other default route (o.o.o.o).I was having trouble getting to websites that took along time to reach or respond.after it failed to reach the website it looked at the other default route and stayed there until so many minutes,then went back to the other default route (my dsl modem)If a website failed all other requests to other websites would fail also until "whatever timed out" Then it went back working fine.
maybe i got it?

I use OSPF as a router protocol, by default it iuses these costs:
1 = gigabit
10 = 100 meg
100 = 10 meg


so a route using 2 gig hops and a 100 meg hop has a cost of 12, while a route with one gig hop and 2 100 meg hops has a cost of 21, so the traffic will take the faster path.

by that theory T1= 999 is not totally off base, but I am surprised it would be automatic

I tried to remain child-like, all I acheived was childish.
