Re: help is neede! [7:43033]

Re: OSPF: Master / Slave relationship
Hi , I agree with priscilla , but doesnt this master/slave relationship change after the slave had sent its dd packets to the master then the master becomes slave and sents the dd packets? can you send me the report of ur sniffer priscilla cause i havent yet been able to see this besides books Priscilla Oppenheimer [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I don't think the master/slave business is related to DR and BDR. It has to do with neighbor adjacency and establishing the protocol for exchanging the link state database. After initializing, two neighbors establish bidirectional communication and then enter the ExStart state. In this state, the routers establish a master/slave relationship and determine the initial database description (DD) sequence number. At first both neighbors will claim to be the master by sending an empty DD packet with the Master/Slave (MS) bit set to one. The neighbor with the lower Router ID will become the slave and will reply with a DD packet in which the MS bit is zero and the DD sequence number is set to the master's sequence number. This DD packet is the first one with actual data, that is, LSA summaries. The routers then know who is the master and who is the slave and enter the Exchange state where they synchronize their link state databases. When I first looked at all of this on a Sniffer I was pleasantly surprised to discover how complicated it is! ;-) It's a little like a TCP 3-way handshake.

Re: 1600 password recovery
hi there , this happens maybe ur emulator is not working properly and isnt transmiting break sequence to the router try reinstalling it or try it with some other machine. try break+f5 or shift+f5 or follow this This is useful if your terminal emulator doesn't support the break key, or if a bug prevents it from sending the correct signal (the hyperterminal under Windows NT used to suffer from this behavior): Connect to the router with the following terminal settings: 1200 baud rate No parity 8 data bits 1 stop bit No flow control You will no longer be able to see any output on your screen. This is normal. Reload the router and press the spacebar for 10-15 seconds. This generates a signal similar to the break sequence. Disconnect your terminal and reconnect with a 9600 baud rate. You should now be in ROM Monitor mode. _/-\__'Cheers' /_\ \-/ | | ""Paver, Charles"" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Hi all!
