HSRP is a Cisco proprietary protocol, so really discussion of it should go to the Cisco newsgroup comp.dcom.sys.cisco . GVRP is (if I have the right abbreviation) the open standard equipment.

I suggest you examine the white papers on the site of Vincent C. Jones, who literally wrote the book on high reliability networking with Cisco equipment. Vincent drops into comp.dcom.sys.cisco once or twice a week, so if the other regulars there don't happen to have useful comments, he'll probably say something within a couple of weeks at most.

Hi !

I planned to install redundant Cisco equipments on my Lan. I would like you to give me your opinion about my configuration. Thank you in advance

I have 2 backbone switches on my LAN. CATALYST 4510R.

For active redundancy, i configured first the vtp mode.

4510_prod and 4510_backup are vtp servers in the same domain. the 4510_prod has a bigger revision version. The synchronization works fine.

For virtual ip addresses, i configured HSRP

For example:

4510_PROD:

interface Vlan50 description VLAN TEST ip address 10.33.150.252 255.255.255.0 no ip redirects no ip proxy-arp standby 50 ip 10.33.150.1 standby 50 priority 100 standby 50 preempt

4510_BACKUP:

interface Vlan50 description VLAN TEST ip address 10.33.150.253 255.255.255.0 no ip redirects no ip proxy-arp standby 50 ip 10.33.150.1 standby 50 priority 10

For Spanning-Tree, i think the better way is to install MST mode on all my Cisco switches.

I defined 4510_prod as root and my 4510_backup as secondary root (for backup)

For 4510_prod:

Spanning-tree mst configuration Name TEST Revision 1 Instance 1 vlan 1-999 Spanning-tree mst 1 priority 4096

and on all my LAN Cisco switches:

name TEST revision 1 instance 1 vlan 1-999

Question: Does i Need to configure the same thing on all my other switches on my LAN? By default, PVST is active.

I cannot delete instance 0. It is normal?

Thank you very much for your help

Greetings

PILU

That would be VRRP.
