Hi all, Have faced some weird problems when working with 4 port BRI module in 3662 router. The 3662 router has 12.1(5)T10 IP Plus IOS.
Some of the problems faced are as under : The "dialer idle-timeout" on dialer interfaces does not work. The connections (ppp multilink bundle) are disconnected after a interval of 150 seconds (the dialer idle-timeout configured value) even though the IDLE time has always been 0 seconds. The "dialer pool-member 1 min-link 1" command simply blocks the B channel of that BRI interface even though there is traffic from a dialer belonging to Pool 1. ( i.e. when "dialer load-threshold 1 either " command has been configured on dialer, yet even after the load on BRI2/0:1 goes beyond 254/255 yet the second B channel never comes up. ) In the trace it shows that the BRI is trying to bring up the second interface but is unable to do so since Both channels are already busy. The most important flaw was : we have configured BRI2/0 and BRI2/1 both as members of Pool1 such that BRI2/0 has priority 100 and BRI2/1 has priority 50. Yet whenever there is interesting traffic for dialer1 (belonging to Pool1) it always tries to bring up BRI2/1 and BRI2/0 is never touched. This behavior is not noticed when BRI2/1 and BRI2/2 are configured members of the same pool (e.g. pool2) with BRI2/1 given the higher priority. ( i.e. dialer2, belonging to pool2, always brings up BRI2/1 first and then BRI2/2) ================================ relevant Configuration is as below : ! interface Serial1/0 bandwidth 2048 backup delay 260 360 backup interface Dialer1 ip address 14.29.0.18 255.255.255.252 no ip mroute-cache no cdp enable ! interface BRI2/0 no ip address encapsulation ppp no ip mroute-cache dialer pool-member 2 priority 50 dialer pool-member 1 priority 100 min-link 1 isdn switch-type basic-net3 no cdp enable ppp authentication chap ppp multilink ! interface BRI2/1 no ip address encapsulation ppp no ip mroute-cache dialer pool-member 1 priority 50 dialer pool-member 2 priority 100 isdn switch-type basic-net3 isdn T310 60000 no cdp enable ppp authentication chap ppp multilink ! ! interface Dialer1 ip unnumbered FastEthernet0/0 encapsulation ppp dialer pool 1 dialer remote-name flex3662vp dialer idle-timeout 150 dialer fast-idle 90 dialer string 0228241482 dialer load-threshold 30 either dialer-group 1 pulse-time 0 ppp authentication chap ppp multilink ! interface Dialer2 ip unnumbered FastEthernet0/0 encapsulation ppp dialer pool 2 dialer remote-name flex3662rt dialer idle-timeout 150 dialer string 0805597611 dialer string 0805597622 dialer load-threshold 192 either dialer-group 2 no cdp enable ppp authentication chap ppp multilink !
