Hello:

I am trying to bridge to locations via a point to point t1. The provider
says that they do no provide clocking on the line. My routers are 1720's
with a WIC T1 interface card in both of them. Does anybody have a good
configuration for this application? I would like to be able to pull DHCP
from the main facility too. Is this possible? Currently I can ping the
serial0 interfaces between the routers, but I cannot see through to the LAN.
I am willing to scrap my current config, it somebody has a working config.

Thank you,

Jason Goddard

Hi,

If the routers can ping each other then you are almost done; maybe you only
need to configure some routing protocol betwen the routers or use static
routes.

Thank you so much. Do you have an example of the static routes? Do I
need to assign an ip address to my fastethernet0 ports? I mentioned
above that I would like to DHCP over them, but now I am just going to
plug my PBX's directly into them. So no need to DHCP. So basicily, I
am creating a tunnel for two PBX's to talk back and forth.

Thank you,
Jason

Hi,

If you just need static routing you only have to insert something like this
(assuming 192.168.1.0/24 is reachable via router A and 192.168.2.0/24 via
router B):

RouterA
ip route 192.168.2.0 255.255.255.0 192.168.0.2 (where 192.168.0.2 is routerB
serial interface address)

RouterB
ip route 192.168.1.0 255.255.255.0 192.168.0.1 (where 192.168.0.1 is routerA
serial interface address)

You can also avoid using an IP Address and use somethink like this (ip route
ip route 192.168.2.0 255.255.255.0 serial<something>

You need to assign an address to your fastethernet interfaces on both
routers (this IP will be the gateway used by your IP PBX) (i.e.
192.168.1.254/24 for RouterA's fa0 and 192.168.2.254/24 for routerB's fa0)


to proxy DHCP requests arriving at an interface use something like this: ip
helper-address <dhcp server address>

Gabriele:

If I understand you correctly, I am plugging the ip address of my IP
PBX's into the route table correct? My main pbx is 10.0.1.28
255.255.255.0. My main router serial interface is 10.0.0.1
255.255.255.252. My remote pbx is 10.0.1.30 255.255.255.0. My remote
router serial interface is 10.0.0.2 255.255.255.252.

Is this correct?

Thank you for your patience I am almost there.

Jason

Hello john,

You should go for routing instead of bridging if possible.

I have not seen this on a E1 or T1 before. Read the article below to find
out more on how to set some kind of clock.I am not sure if this is what you
are looking for.

Hi,

You can't have two identical prefixes at both routers (without bridging,
using NATor proxy ARP at least)... so, if you do not want to bridge, you
have to use something like this
-----------------------------------------------------------------
RouterA
interface serial0
ip address 10.0.0.1 255.255.255.252

interface fa0
ip address 10.0.1.254 255.255.255.0

ip route 10.0.2.0 255.255.255.0 10.0.0.2


RouterB
interface serial0
ip address 10.0.0.2 255.255.255.252

interface fa0
ip address 10.0.2.254 255.255.255.0

ip route 10.0.1.0 255.255.255.0 10.0.0.1
------------------------------------------------------------------

If you want (you shouldn't) you can used proxy ARP while having the same
subnets on both routers (or better use bridging)

Gabriele

There is no clocking because its a point to point T1. I set one of
these up recently. It was an AT&T provided line. One router provided
teh clock, the other got it off the line.
