RE: (usr-tc) Config for Dual BRI Cisco to TC
Thanks for the input. I am on the right track. I just need help with the "mojos"... I've got 1 BRI multilinking perfectly, need some help from someone who has this working for 2 or knows the Cisco config parameters Thanks John -----Original Message----- From: Jeff Mcadams [mailto:jeffm@iglou.com] Sent: Monday, June 19, 2000 11:51 AM To: usr-tc@lists.xmission.com Subject: Re: (usr-tc) Config for Dual BRI Cisco to TC Also sprach Verreault, John
I am trying to get a cisco 4000 with 2 BRI interfaces to connect to a Total Control Chassis. (I am not sure if you can MPP over both BRI's, if not I would settle for MPP for each BRI and load balance over the 2 multilinked BRI's)
There should be no problem with multi-linking two BRI's together for a 256kbps connection. There's no theoretical limit to the number of channels you can link together...though there are definitely practical limits. :)
I am having some problems with the second BRI. I cannot get a stable connection.
I am assigning the BRI interface a static IP and specifying the route with radius.
OK...I don't have much Cisco dial mojo, but you seem to be going wrong on the concepts here. If you're running multi-link over 4 channels (2 channels per BRI, 2 BRIs), then you probably shouldn't be giving an IP address to a specific BRI. You should have some sort of "virtual" interface or suchlike that the BRIs would be attached to in some way, you would give the IP address to the "virtual" interface (maybe a dialer interface? like I said...I don't know Cisco dial well at all). Then, when you get both BRIs assigned/attached to this "virtual" interface (whatever it may be called), then it *should* multi-link across the BRIs with no problem. There's nothing inherent about multi-link that makes it only function within an individual line (BRI). In fact, you can run multi-link across multiple modems, across multiple T1's, even, theoretically, across multiple L2TP or PPTP connections if you *really* wanted.
Should the second interface have the same static IP address or a different one.
The second BRI, like the first, shouldn't have an IP address itself at all most likely. -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

"ppp multilink" is one of the magic words. When I used a Cisco 804 at home, I remember I had to put "ppp multilink" on both the BRI0 and the Dialer1 interface for it to be happy. Here's the abbreviated bits of one of my old 804 configs: map-class dialer DialerClass1 interface BRI0 no ip address encaps ppp ppp multilink dialer pool-member 1 interface Dialer1 ip address 10.0.0.1 255.255.255.0 (or ip unnumbered ethernet0 if you're doing it that way) encaps ppp ppp multilink dialer string 5551212 class DialerClass1 dialer idle-timeout 600 ppp pap sent-username blah blah blah... (I was dialing into another 804, not a Total Control, but for at least the multilink setup that shouldn't matter.) The Cisco dialer stuff is kinda voodoo-ish to me still; I mostly pulled this out of the Cisco 804 manual, Dejanews postings, and CCO searches... it worked so I left it. Then I got DSL and I don't need the 804 anymore. Anyone wanna buy it? :) Mike Andrews (MA12) * mandrews@dcr.net * http://www.bit0.com/ VP, sysadmin, & network guy, Digital Crescent Inc, Frankfort KY Internet services for Frankfort, Lawrenceburg, Owenton, Shelbyville www.fark.com: If it's not news, it's Fark.
