RE: policy route [7:21044]
my appologies. i always presumed it worked in the same way as unix-HA... thanks for the correction steve From: Kent Hundley Reply-To: Kent Hundley To: [EMAIL PROTECTED] Subject: RE: policy route [7:21044] Date: Wed, 26 Sep 2001 13:52:32 -0400 Stephen, Your statement is incorrect. Enabling HSRP on a router does not cause the standby router to send all packets to the primary. The only things that enabling HSRP does is: 1) Enable the primary router to answer arp replies and accept/return packets for the virtual IP address (it does this by creating a virtual MAC to match the virtual IP) 2) Enable a hearbeat signal so that secondaries can takeover for the primary in the event of failure Neither of these things has any effect on the backup HSRP routers ability to forward IP packets as it normally would. You can still use the secondary HSRP router as you normally would by sending packets to its real IP. The secondary routers will forward packets sent to them based on the contents of their routing table, they will not simply send all traffic over to the primary router. I've tested this in real world scenarios before and just re-confirmed it in my lab. -Kent -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Stephen Skinner Sent: Wednesday, September 26, 2001 8:12 AM To: [EMAIL PROTECTED] Subject: RE: policy route [7:21044] i have to diasgreeevery 3 secs a pulse is sent from the active to standby.even if you have a route connected to your standbywhen thestandby gets any routed packets HSRP (which is layer 1/2) will send it to the active master..this wil then route the packets accordingly... i`m told ther is a way around this but you will have to search the archives...it was only a couple of weeks ago Cheers steve From: Jim Bond Reply-To: Jim Bond To: [EMAIL PROTECTED] Subject: RE: policy route [7:21044] Date: Tue, 25 Sep 2001 17:15:07 -0400 I have to disagree.
