How do I Configure a VWIC 2MFT-T1 controller on a cisco 1700 router???

[ixleplix]

I have two identical Cisco 1700 routers IOS 12.3(5b)and 2 T1's. I need to configure them to use both T1's simultaniously. At the moment I have them set up so that I can reach one (it is connected by a single T1 to the other which is a dead end [to keep from confusing the other routers]). However, I can't seem to communicate across the T1 to the other router. Below is the config and show int from the one I'm working on right now.

I'm new at this type of router config and could use all of the help you could offer.

Thanks in advance for any help.

1) A robot may not injure a human being or, through inaction, allow a human being to come to harm.

2) A robot must obey orders given it by human beings except where such orders would conflict with the First Law.

3) A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

If what you're saying is that you have two routers, and two T1's, and EACH ROUTER is connected to one of the T1's, then there is one more question. Are both T1's to the same provider? If so look into GLBP for load balancing. I've posted some pretty lengthy things on GLBP at thread557-808940 .

Hope that helps...

 

[ixleplix]

Sorry If I wasn't clear enough. The final config is going to be Router A connected by 2 T1's to Router B. Not for failover but to use as a single trunk.

I'll go ahead and look at the link you posted too.

Thanks

Also, the only reason I'm not using both T1's to start is that I can't move them both over to the new routers until it is working. They are to replace a pair of old Cisco 1601's and we've also added one more T1. Origionally it was only a single link.

Thanks again

Solved it!

Ok, I cleared the settings on the Controller and the serial interfaces so I was at the basic config and then entered these commands.

on router a

config t
controller t1 0/1
shut
channel-group 1 timeslots 1-24
no shut
controller t1 0/0
shut
channel-group 1 timeslots 1-24
no shut
int multilink1
shut
ip address 192.168.1.1 255.255.255.0
no cdp enable
multilink-group 1
no shut
int ser 0/0:1
shut
encapsulation ppp
no fair-queue
ppp multilink
multilink-group 1
no shut
int ser 0/1:1
shut
encapsulation ppp
no fair-queue
ppp multilink
multilink-group 1
no shut
end
write mem




on router b


controller t1 0/0
shut
channel-group 0 timeslots 1-24
no shut
int multilink1
shut
ip address 192.168.1.2 255.255.255.0
no cdp enable
multilink-group 1
no shut
int ser 0/0:0
shut
encapsulation ppp
no fair-queue
ppp multilink
multilink-group 1
no shut
int ser 0/1:0
shut
encapsulation ppp
no fair-queue
ppp multilink
multilink-group 1
no shut
end
write mem

I was pointed in the right direction by thread557-762839


This has solved my issue; by using ppp multilink I have both T1's on each end using only one IP address. From what I understand this will automatically load-balance as well as allowing traffic to flow through both T1's.

I still have to configure the default route and a few minor details but this was the trouble part.

1) A robot may not injure a human being or, through inaction, allow a human being to come to harm.

2) A robot must obey orders given it by human beings except where such orders would conflict with the First Law.

3) A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

 

[ixleplix]

router b

should have these commands listed too:

controller t1 0/1
shut
channel-group 0 timeslots 1-24
no shut

Sorry I missed that

1) A robot may not injure a human being or, through inaction, allow a human being to come to harm.

2) A robot must obey orders given it by human beings except where such orders would conflict with the First Law.

3) A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

Look up multilink interface. That is how you bond 2 t-1s together to act as a single trunk.
