Hi have the folloing problem on STP...
-------------SiteA: Cisco2950--------
| | 10mb| |10mb | | Site B: Cisco3550 ---------100mb-------------- Site C: Extreme Summit Switch
Site A-B primary circuit. (10mb LES10 circuit) Site A-C Secondary circuit. (10MB LES10 Circuit) Site B-C - 100MB connection
But with normal STP config it sees SiteA - SiteC as the primary (should be secondary) have tried setting priority on STP but no use... Any Ideas?
Thanks in advance.
