Group,
Can't seem to get this working: r1 is connected to r2 via s1 and br0 (legacy
ddr) for backup with both running eigrp. The isdn works fine when tested
with floating statics and backup interfaces. But with the dialer watch isdn
just will not dial, although 'debug dialer' shows dialer watch recognizing
the primary link going down:
r1(config)#int s1
r1(config-if)#sh
r1(config-if)#
02:14:18: DDR: Dialer Watch: watch-group = 10
02:14:18: DDR: network 192.168.20.0/255.255.255.0 DOWN,
02:14:18: DDR: primary DOWN
02:14:18: DDR: Dialer Watch: Dial Reason: Primary of group 10 DOWN
02:14:18: DDR: Dialer Watch: watch-group = 10,
02:14:18: DDR: Dialer Watch: watch-group = 10
02:14:18: DDR: network 192.168.20.0/255.255.255.0 DOWN,
