Bridging and HSRP [7:39525]
Greetings all, I've a 6509 with 2 sups and MSFCs, running hsrp between both MSFCs. Routing 5 vlans, two of those 5 vlan are also bridging decnet. When I've the standby interface up, users can't get out, if I shutdown the standby interface all is good. According to Cisco I've to enable "standby use-bia" feature to prevent this problem. Have you guys seen this before, and what causes this problem? Just looking for some education and solutions. Thanks..Nabil - Hope I made my problem clear!

RE: Bridging and HSRP [7:39525]
This is more of a question on top of this question? If I have dual Sup's in a 6509, why not just run high availability and not worry about HSRP ? Does HSRP give you something that High Availability doesn't ? Once again, this is a question, not a statement or recommendation.

RE: Bridging and HSRP [7:39525]
It relates to DECnet using the mac address of the interface to derive the DECnet address. You need to configure DECnet, then HSRP using standby use-bia. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, March 26, 2002 8:26 AM To: [EMAIL PROTECTED] Subject: Bridging and HSRP [7:39525] Greetings all, I've a 6509 with 2 sups and MSFCs, running hsrp between both MSFCs.

Re: Bridging and HSRP [7:39525]
See if this helps explain what your seeing. I haven't seen the decnet problem myself but I have seen the use of the bia "fix" strange HSRP problems. It's a tool I keep in the back of my mind Dave http://www.cisco.com/warp/public/619/hsrpguide4.shtml#3 "[EMAIL PROTECTED]" wrote: > > Greetings all, > > I've a 6509 with 2 sups and MSFCs, running hsrp between both MSFCs. > Routing 5 vlans, two of those 5 vlan are also bridging decnet.

Re: Bridging and HSRP [7:39525]
Hi, When using DECnet, the MAC address is changed depending on the DECnet address. You need to use the HSRP use-bia feature with DECnet. HSRP then uses the DECNet MAC address. From http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/decnet.htm DECnet hosts do not use manufacturer-assigned Media Access Control (MAC)-layer addresses. Instead, network level addresses are embedded in the MAC-layer address according to an algorithm that multiplies the area number by 1024 and adds the node number to the product. The resulting 16-bit decimal address is converted to a hexadecimal number and is appended to the address AA00.0400 in byte-swapped order, with the least-significant byte first. For example, DECnet address 12.75 becomes 12363 (base 10), which equals 304B (base 16). After this byte-swapped address is appended to the standard DECnet MAC address prefix, the address is AA00.0400.4B30. --- "[EMAIL PROTECTED]" wrote: > Greetings all, > > I've a 6509 with 2 sups and MSFCs, running hsrp > between both MSFCs. > Routing 5 vlans, two of those 5 vlan are also > bridging decnet.

Re: Bridging and HSRP [7:39525]
It's a good question though. When the 6500 first came out there was no config-sync or SRM which was a problem if you had a flexwan. config-sync was nice for flexwan support but still required HSRP. SRM is what I have been doing for a while now and it works well and there is no HSRP necessary, one less feature to find bugs in!! my $.02 Dave "Roberts, Larry" wrote: > > This is more of a question on top of this question? > If I have dual Sup's in a 6509, why not just run high availability and not > worry about HSRP ?
