Thanks Rajan, I thought I had created the pattern in the same partition. Is it because I used wildcards and the 9.@ wildcard trumps it? Im not sure how to do the second part of the answer. I can create a new partition and create a pattern with that partition, but Im not sure how the phone CSS bit works. Steve. ... View more

Thanks again Mr Valencia... Ran the DNA (Had to google it) and found that it matched with pattern 9.@ Partition = Local-Rate-Access-Part Not sure how I over ride that? Steve. ... View more

We are going to do a bit of testing in the next couple of weeks. shutting down links etc. I think going forward I can recommend an extra fibre be installed between the 2 switches and also have a chat with Virgin as to why we have HSRP as well as OSPF. Thanks for all the help, been a while since I had to look so deeply into any network issue. Steve. ... View more

I think that is what I suspect Jon. There are static routes on the switches and OSPF then advertises them around the network. Its been years since I did my CCNA and I had forgotten all about Administrative distances. Looking at the switches quickly I can see they all appear to be default ADs. So your right. So if I make the route I want lower, it should always go that way unless its down. Although...Just thought..We are using HSRP, so that would be the advertised route. So I presume OSPF will pick either route. Steve. ... View more

Yes, sorry, its all up and working now. Just cant figure out why it would report the backup switches vlan interface IP address as one of the hops. Steve. ... View more

Here is a tracert on the live network....It shows it going correctly, but then goes to the address of the vlan interface on the backup switch. Very confusing. Could it be that OSPF sees the 1gb link to the other switch as a faster route than the 100mb link to the firewall? Or is it that the vlan is on both switches and it doesn't matter what vlan interface it uses?

Good point.... This was implemented by a predecessor, so I'm trying to get my head around it. ... View more

Thanks for the quick reply guys. Philip, that does make good sense. So best way forward is to put another link in between the switches in an etherchannel. To answer to some of the questions....Yes it is OSPF between the routers and the switches. The switches have vlan interface ip addresses on them. The link between the 2 switches is a single fibre trunk. The virgin routers are in an active and standby state. using HSRP again I believe. Also the other thing to mention is that the ASA firewall apparently failed over to the standby one. I don't manage them, its a third party company, so cant see the config or logs. Steve. ... View more
