Re: HSRP Lab... :-(...u need a break dude
I simulated your situation in my lab. I was actually trying out VRRP.I had a " transparent proxy arp" running. later , i dismantled the whole thing to factory and noticed that the only way to achieve what u have achieved is by configuring static routes. Check your route tables. -Original Message- From:Bharat Suneja [EMAIL PROTECTED] Sent:Tue, 17 Oct 2000 16:46:48 -0700 To: [EMAIL PROTECTED] Subject: Re: HSRP Lab... :-(...u need a break dude Pradeep, That was a test in the lab.

Re: HSRP Lab... :-(...u need a break dude
Pradeep, Here is the config : E0 of router B is on the same segment. Here is the IP config : Router A: E0 - 192.1.1.1, 255.255.255.0 S0 - 192.3.1.1, 255.255.255.0 Router B: E0 - 192.1.1.2, 255.255.255.0 S0 - 192.2.1.1, 255.255.255.0 Local PC: 192.1.1.20, 255.255.255.0, Default Gateway 192.1.1.1 Router C: S0 - 192.3.1.2, 255.255.255.0 (is connected to S0 of Router A) S1 - 192.2.1.2, 255.255.255.0 (is connected to S0 of Router B) E0 - 192.4.1.1, 255.255.255.0 (is connected to Remote PC) Remote PC: 192.4.1.20, 255.255.255.0, Default Gateway 192.4.1.1 (Router C) Router A, Router B & Local PC are connected to a hub.

Re: HSRP Lab... :-(
If you have a second gateway set, a host will eventually use that second gateway. HSRP works a lot faster than this, since it doesn't have to wait for the ARP to timeout. Other than that, I don't see how RouterB would route the packets. I don't think PCs broadcast for default gateways, but I could be wrong.

Re: HSRP Lab... :-(...u need a break dude
Bharat, I think you are still working the night shifts and need a break. PC on remote router WILL NOT be able to "talk to " the Win 95 client connected to the hub. Period. If HSRP is not configured And If There is one and only one ( Router A ) default gateway configured And if There is no entry of Router B interface as gateway 2 ( multiple gateways for one client is possible) Then Win 95 will not talk to remote PC But if Win 95 configured with D/G -II = Router B E0, Then They will Else if HSRP end if Hope that helps.It will -Original Message- From:Bharat Suneja [EMAIL PROTECTED] Sent:Thu, 21 Sep 2000 15:52:59 -0700 To: [EMAIL PROTECTED] Subject: HSRP Lab... :-( Hi all, I was doing a HSRP lab. Two routers have their E0 connected to hub. A Win95 PC is also connected to the hub. S0 of both routers connected to a remote router with a PC on E0 of remote router. Routing Protocol: EIGRP. Now, before configuring HSRP on the local routers, if I disconnect E0 on Router A from the hub, the PC connected to the hub should not be able to forward packets because its default gateway (Router A) is down.

HSRP Lab... :-(
Hi all, I was doing a HSRP lab. Two routers have their E0 connected to hub. A Win95 PC is also connected to the hub. S0 of both routers connected to a remote router with a PC on E0 of remote router. Routing Protocol: EIGRP. Now, before configuring HSRP on the local routers, if I disconnect E0 on Router A from the hub, the PC connected to the hub should not be able to forward packets because its default gateway (Router A) is down. However, I find that the PC can still communicate with the remote network - the second router (Router B) forwards the packets!! This is something I didn't know before - and the OS on the PC is Windows 95!!! My questions: 1. Is this a Win95 feature ??? (doubtful as it sounds!!) 2. Is this something to do with RDP ??? 3. Is this something to do with ARP ??? (PC broadcasts for default gateway and Router B replies when router A is down??). If 2 and 3 are true, what's the purpose of HSRP ???
