Hi ,
I had 2 unit 1720 router configured for DDR. I
found some bug on dialer-list command.
Router 1 had no problem to initiate the DDR when
souce is 10.10.10.11 or 10.10.10.90.
But Router 2 had problem to intiate the DDR from
network 202.190.x.0 and 10.10.10.0 to netowrk
10.10.11.0
After wasted my whole days then , I decide to
change the "dialer-list 1 protocol ip list 101" to "dialer-list 1 protocol ip
permit"
and it works !!
By right "ip permit" will allowed all IP protocol
to initiate call , but the result is only network 202.190.X.0 and netowrk
10.10.10.0 can initiate DR to netowrk 10.10.11.0
I had done this configuration before on CIsco 2500
but never had any problem , why ?? The 1720 IOS is Version
12.0(5)T1
[ ROUTER 1 ]
access-list 10 permit 10.10.10.11
access-list 10 permit 10.10.10.90 dialer-list 2 protocol ip list 10 [ ROUTER 2 ]
access-list 101 permit ip 202.190.165.0 0.0.0.255
10.10.11.0 0.0.0.255
access-list 101 permit ip 10.10.10.0 0.0.0.255 10.10.11.0 0.0.0.255 dialer-list 1 protocol ip list 101 [ ROUTER 2 ] Modified
access-list 101 permit ip 202.190.165.0 0.0.0.255
10.10.11.0 0.0.0.255 access-list 101 permit ip 10.10.10.0 0.0.0.255 10.10.11.0 0.0.0.255 dialer-list 1 protocol ip permit. |
