please clear my concept on frame-relay and ISDN [7:17649]
Hi.. Dear all, I don!t understand this. Hope u can clear my concept. I have a 1700 router in remote office(Milan) which is connected to a main router in London via a Frame-relay link in interface s0.1. My IT colleague (Milan) told me that the frame-relay line was cancelled last week by ISP!s mistake and the link has been running on ISDN since the 20th August. Until now it is still in ISDN. Now I found that the Milan(remote) router is still connecting main router via the same interface s0.1. When I type !'sh int s0.1!( shown below, it still show me that it is a frame-relay. 1)How do I know whether it is on ISDN or not, what command? 2)What is the difference between frame-relay line and lease line. Can I say that previously the line is a frame-relay leased line and now it is a frame-relay ISDN line?? 3)How can they change the line into a ISDN using the same interface? I thought it should have a ISDN back up interface?? Can the ISP vendor change the circuit to ISDN at their site without coming the Milan office? Or the Remote(Milan) office change a ISDN!s CSU/DSU and made it to a ISDN line?

Re: what is loopback interface for ? [7:9493]
Hi.. Sorry, I need a few more questions to verify whether my understanding on loopback is correct or not? Pls answer it. 1) If I have two router A (loopback=192.168.0.1/32) and B (loopback192.168.0.2/32), Router A's S1 int 100.100.100.1/24 is connected to Router B's S1 100.100.100.2/24. There are no more other connection. If S1 of B is down. Can I still telnet from A to B using B's loopback address. 2) If Router A and B have another connection. Router A's S2 int 100.200.100.1/24 is connected to Router B's S2 100.200.100.2/24. If S1 of B is down. Can I still telnet from A to B using B's loopback address? 3) If Router A doesn't have loopback int configured. Can we still telnet from A to B? 4) Whether the loopback IP address need to be in order or same network? Let say Router A's loopback is 192.168.0.1/32 and Router B's loopback is 20.20.20.1/8. Can we still telnet from A to B? 5) If I configured A's loopback IP to be 192.168.0.1/24, can we still configured B's loopback to be 192.168.0.2/24? Note: there are in same network. _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

what is loopback interface for ? [7:9493]
Hi, I always wonder what is loopback interface for? Can anyone explained its function? Can we don't configure the loopback interface. Our WAN Lookback always start with 192.168.X.X why? Must we use private IP? I found I can telnet to a remote router using its loopback IP. But I wonder How I route as it always have the subnet mask of 255.255.255.255.

What is the better way to do it. How about in Cisco way? Any idea? If by proxy you mean default router, go to http://www.cisco.com/ and search for HSRP. If you're thinking of an HTTP proxy, your best bet is to forget about 10.0.0.5 and just declare a single proxy in your DNS zone file, with 2 addresses, as in proxy.your.domain.goes.there. IN A 10.0.0.6 IN A 10.0.0.7 Then you can just configure proxy.your.domain.goes.there. as the HTTP proxy in your users' browsers and forget that there are 2 addresses behind that name. -- Someone approached me and asked me to teach a javascript course.

what is official cisco course book for routing and remote [7:7503]
what is official cisco course book for routing and remote access exam? Remote Access- Building Cisco Remote access network by Catherine Paguet or CCNP Remote Access Exam guide? Routing-Building Cisco Scalable Cisco Network by or CCNP routing exam guide?? Susan From: John Andrews Reply-To: John Andrews To: [EMAIL PROTECTED] Subject: CCNP ?? [7:4789] Date: Wed, 16 May 2001 22:37:01 -0400 I have a question or two. I am in the near future planning on taking the CCNP switching exam. My question is this? How through is the test compared to the sybex book? Will that, plus the boson tests prepare me adequately enough to pass the test and in addition to the edge tests that are included with the book? Also, what are the main areas covered? I am NOT asking for specific questionsbut generalities only. Something like VLANS were a large portion of the CCNA exam. I am suspecting that rp's, switch types, commands, pim sparse and dense modes are the main portions. Or at least this is what I am getting out of the sybex book. Am I seeing this wrong or am I on the right track? Thanks, J (the one who will be glad when this test is done) Have a great day!
