Re: OSPF max Router-LSA links [7:72024]

The original question (as I understood) was about a single LSA that is larger than 1500 bytes (think Type 1 LSA for a router with 200 interfaces). I can't see how such an LSA could be divided into multiple OSPF messages so the only logical (implementation independent) solution seems to be to fr

Re: ISDN Port goes to Deactivated mode [7:72022]

Probably layer 1 and 2 are deactivated by the Telco. It's better to use a dialer interface as backup of a serial line. Then L1/2 stays up. Refer to other ISDN thread as well. If you don't want to do that, try to change the TEI negotiation. Cisco's default is TEI negotiation when the router is powe

RE: Maximum segment size in TCP [7:72030]

I have seen a similar issue with a VPN connection. The problem was caused when an NT admin wrote a batch file that did a large FTP across the link every 45 minutes. The large volume of traffic caused the router cpu to spike due to the encryp/decryp load… hence slow performance. I would try to chec

Re: ISDN case... [7:72017]

Hi Heiman, You won't get a bill: there won't be any ISDN layer 3 call: only your ISDN bearer, so layer 1/2 will come up. Only when your serial goes down, an ISDN call will be made and then you have to pay. Eric - Original Message - From: "H T" To: Sent: Tuesday, July 08, 2003 3:05 PM S

RE: ISDN Port goes to Deactivated mode [7:72022]

I have experienced the same problem and would really like to see what the others have to say. While testing, I put my router with a BRI-1B-S/T card behind a PBX with an NTI card and the problem vanished. This led me to believe that the problem has something to do with the telco. I *think* the

RE: Maximum segment size in TCP [7:72030]

A host uses the TCP maximum segment size option to specify the max size of TCP segments (packets) that it can accept. In the case where you have the slow response time, the mainframe is saying that its max segment size is 4056 bytes, which means that it can accept packets of that size (with that mu

Re: ISDN case... [7:72017]

This is normal behaviour: if you configure BRI as backup, it will go in standby mode and line protocol goes down. You can avoid this by configuring a dialer interface as backup. Then the dialer interface will go in standby mode, but the BRI stays up!! This is preferred since: 1. some Telco's will l
