I'm hoping somebody can advise me on an issue I have?We have two data centre's connected to an MPLS cloud. Routes are re-distributed from BGP into EIGRP at both data centres. The routes are learnt as external so get a 170 AD in EIGRP for each DC whic...
This was a tricky one to catergorise as it comes under, LAN, WAN and VPN.Please see attached doc.I am planning to connect a number of global branch office sites via DMVPN. Each will have a prefered DC based on geo location and this will be prefered a...
Hi,I am trying to map out a remote network (no physical access) using cdp as we have a suspected stp issue.Something is throwing me though, we have multiple switches connected to the same local interface as shown in cdp - how can this be? I thought c...

In the end I had to jump on a plane to solve this one!It turns out that the gigstack modules get very messy when it comes to STP, especially so if the gigastacks have not been cabled properly as the specs for them are very specific - easy for somebod...
No hubs.I have found out they are using the older GBICs and splitting the copper links A/B between different switches.Is this a normal practice? I thought A and B was tx rx?
I had a similar issue a couple of weeks ago with one of our 6509's in a VSS configuration. Upon reboot the config register would be lost and boot straight into rommon but we could easily set it back to 0x2102 and then boot the IOS. After an unspecifi...
