Hi,I'm having a weird situation with a Cat4948 and a IOS upgrade I'm trying to do: after reloading, passing all of the hw tests and presenting the auth prompt, it reboots itself. I had to cancel the boot, enter rommon and issue a boot command to star...

Hi!I've encountered a problem trying to configure something like this in a Sup720 with IOS 12.2(33)SXI2a:router(config-if)#ipv6 address 2001:DB8:CAFE:CAFE::1/56router(config-if)#ipv6 nd prefix 2001:DB8:CAFE:CAFE::/64so the idea is to have a routed /5...

Hi all!I have a problem puzzling me up for a long time now. I have a 800 series router connected to Internet through ADSL. This line is used as a backup link to our data center from our main office. To accomplish this in a secure and transparent way ...

Hi!I'm trying to get a VPN connection working, and for now, it's impossible. The situation is that I have a 2821 with two GbEth interfaces, one inside and the other outside. But the outside is not a real "outside". It is a connection to our providers...

Hi all,I have a question regarding our BGP configuration that's getting me mad. We have two 7604 doing eBGP with three providers and iBGP between them.This is our config for the iBGP peeering (some data changed to protect the innocent)router1:router ...

Yes, it works, just it is not as "elegant" as doing it all in the interface config, and not having to redistribute the static in OSPF. Just an opinion. I like more the nd prefix solution.Anyway, know something on how this issue is going to be dealt w...

Hi, and sorry for the delay. Local holidays here.About your questions:1.- No, we are not doing OSPF in the servers. The router announces the /56 through OSPF. Servers know nothing about routing.2.- That's correct, but having to define 250 static rout...

Well, maybe I didn't explain it very well. In fact, it's the opposite that you comment: what we want is the servers to get an auto /64 address from the same /64. Then each customer can assign statically any address they want to their server from a di...

Hi, Ole,the reason for doing it this way is that if I configure a /56 in the interface and announce a /64 with nd prefix, I can have SLAAC working and a lot less manual static routes defined for the other /64s. Let me try to explain:I have about 200 ...

Thank you for your efforts. The fact is that this behavior really annoys me, because I expected it to work like in the 4948s and I've planned with it in mind, only to discover this "feature" on the 6500.Given that your test worked fine in a 3745, I p...
