BGP Table and SNMP [7:75016]
Hi all, I wonder if any of you have succesfully retrieved the BGP table from a Cisco router using SNMP?. I read a lot of documents and tried a lot of MIBs/OID without any success. I used the MIB navigation tool at the Cisco TAC but I did not find something really useful. I only could read the peerings, uptime of the BGP session and few more thing. By the moment I think it should be done using snmpwalk, am I right? FYI, I do have the full routing table in one of my routers (IOS 12.2.6) Any help will be appreciated.

Accounting. Pay-per-use service [7:72690]
Hello, I wanted to hear some suggestions from you in this case: My company is thinking to add an Internet product where we can charge the customer regarding the bandwidth usage, something like "pay per use". Do you have any experience about it?. I would like to hear some recommendations like what software you are using, or if this products is just a headache and does not worth the time for implementing it. I have used Netflow just for traffic analysis, never for accounting, can I do this using netflow or there are other software/methods?

Re: 802.1Q trunking on 2500?? [7:56690]
Hello, Well, the link provided below is really good, I didn4t know it. However, I do have a question: I searched for ISL feature with the router 1750 selected, and it was found, then I repeated the search selecting the router 1751 (since 1750 is discontinued) and it looks there is not ISL support avalaible for this model (there is only 802.1q support). Don4t you think there is probably an error?. Which is the smallest router than can support ISL or 802.1q?

BGP Question [7:38858]
Hi all, I am having a BGP problem, and I am not sure how to solve it. Like Jeff Doyle's book says: BGP is not a difficult problem, the problem is the scenario. This is the scenario that I have: --- | I N T E R N E T | --- |Link A |Link B || --- Link E --- | AS 1 | -- | AS 3 | |Link C | Link D | | | I am here| When all links are up everything works fine. The problem is: When Link "B" goes down, there is not any traffic on Link D. In this case Link C gets full and my customer start to call me!. I know it is because there is one more AS hop to reach AS 1, one of the BGP metrics is the amount of AS hops between links. I can manually add one or two prepends for AS 3 and the traffic goes ok, I am taking advantage of Link E My question is: Is there any way that this can be done automaticly?, do I have to use BGP communities? Thanks in advanced, any approach is appreciated.

Re: BGP and ip load-sharing [7:28960]
Hello, Thanks for answering me. I am using BGP because we have 2 Internet access and my customer has 2 providers too. Then, we have to use BGP This is the BGP configuration neighbor xxx.xxx.xxx.xxx description eBGP with Mycustomer neighbor xxx.xxx.xxx.xxx ebgp-multihop 2 neighbor xxx.xxx.xxx.xxx password 7 - neighbor xxx.xxx.xxx.xxx update-source Loopback1 neighbor xxx.xxx.xxx.xxx version 4 neighbor xxx.xxx.xxx.xxx maximum-prefix 8 I don't know why the packets that I am sending to my customer are not simetric in both links. However, the customer sends to me almost the same amount of traffic in both interfaces Thanks Alejandro MADMAN wrote: > > First problem, BGP doesn't load share but with IOS you can source an > interface like a loopback, see BGP and loadsharing. > > If you have two parallel paths to a single provider why are you doing > BGP???

BGP and ip load-sharing [7:28960]
Hi All, This is my first message in the list. I am running a BGP session with a customer. It has 2 serial links with us (Each link of 2 Mbps). The customer and me have selected per-packet sharing in order to balanced the link. In this moment, the traffic that comes from the customer is very simetric in both links, however, the traffic that is sent to the customer from us is not simetric. As far as I know (if I am not wrong), if we are using load balacing per-packet, the incoming and outgoing traffic should be very very similar, right?. Why only the incoming traffic is simetric in this moment. This is the configuration for both interfaces in my router: interface Serial2/0 description Link 1 bandwidth 2048 ip address xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx no ip directed-broadcast ip load-sharing per-packet no ip mroute-cache load-interval 30 no cdp enable hold-queue 1024 out ! interface Serial2/4 description Link number 2 bandwidth 2048 ip address xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx no ip directed-broadcast ip load-sharing per-packet no ip mroute-cache load-interval 30 no fair-queue no cdp enable Any ideas? Thanks Alejandro Acosta P.D. I am using IOS 12.0(7)T Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=28960&t=28960 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
