Hi, All: I am tring to use STP function on bridge device that refer the BRIDGE-STP-HOWTO. And I use PING program to test it from PC1 to PC2. But the forward function is become too long when bridge topology change. How can I tuning the STP to make client connect to another again faster? I have been use follow command. But it seen not this issue. Bcause, if I run " arp -d " on PC1 (flush the arp table) and the reply will be immediately.Or if I run one ping from PC3 to PC2 (PC3 didn't have PC2's arp entry). When PC3 get reply from PC2 and then the PC1 will also get reply immediately. Does any one know what's problem? The command for adjust forward dely : /usr/sbin/brctl setbridgeprio mybr 0 /usr/sbin/brctl sethello mybr 1 /usr/sbin/brctl setmaxage mybr 4 /usr/sbin/brctl setfd mybr 4 /usr/sbin/brctl stp mybr on Two bridge machines are install with linux-2.4.26 and use the ebtables patch (ebtables-brnf-6-vs-2.4.26). Network environment: PC1 --------- Bridge 1 -------- PC2 |----- Bridge 2 ---| PC3 ---- Very thank for your help Regards, Matt. --------------------------------- Do you Yahoo!?
