RE: LMI question [7:14206]

2001-08-01 Thread Michael Eckhoff
LMI is a switch to router protocol. sub-interfaces just bind to individual DLCI's. Therefore, they don't have their own LMI configuration. Only the serial trunk does. Mike Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=14611&t=14206 -

2001-08-01 Thread Michael Eckhoff
You need to clarify if you're running BGP on the firewall as well. If you are, quit it. If not, then your BGP peers will need to communicate through the firewall, so yes, you will need to allow them TCP access to each other. As for someone probing your firewall to see if you are doing BGP troug

2001-08-01 Thread Michael Eckhoff
8228 MAUs are made up of micro-switches that get charged (initially) by a 9 volt battery and later kept working from the power of the ring. If it's real old, you may need to recharge it. Never charge a port that is already in the ring - you'll beacon it. Also, you don't need to change RI/RO. W

Sure, the first one that responds wins. They don't even need to be on the same physical network. Let's say that you have DHCP Server #1(10.10.10.10) in the production site and DHCP Server #2 (192.168.1.1) at your DR site. The router is configured with a helper address for both: ip helper-addr

Crud - I hate replying to my own messages. But I forgot to add something: If you are using Paradyne FrameServer DSUs, you have another thing to worry about. They tend to do auto-negotiation of LMI out their WAN side and Cisco LMI towards your router. With this setup, you are getting your LMI f

Re: LMI Clarification [7:14490]

2001-08-01 Thread Michael Eckhoff
If your LMI doesn't match, it just plain won't come up. Both the router and the switch must agree on their link management packet details, or they won't be able to communicate. Now, what could cause things to bounce is if there is a physical layer circuit problem and you're droping LMI packets.

2001-08-01 Thread Michael Eckhoff
I think that your explanation is pointing more at point to multipoint. It's somewhat confusing. Let's say for instance we have this: Hub (10.1.1.1/24) -> Frame Circuit -> DLCI 20 Site1 (10.1.1.2/24) -> Frame Circuit -> DLCI 30 Site2 -(10.1.1.3/24) > Frame Circuit -> DLCI 40 Notice that each o

If I understand what you're saying properly, you probably have a max-paths problem. EIGRP only handles a max of 6 paths very well. Anything over that and it starts getting pissy with you. If you list out the EIGRP topology database, you will see that for every route, you will have an entry for

There are a couple ways to do this, but first let me make sure I understand what you want to do. Lets say for instance that "Server A" is really a firewall or external gateway to the Internet. You want any traffic that you do not claim in your routing tables to flow to this device. On the r
