I am using channelized PRI as backup for channelized E1. Channels in E1 are grouped to make a multilink according to different locations. In case a multilink goes down PRI should fire one of its channels.
I am confused about the configuration for dialer map.
Following is the config:
interface Serial5/7:15
no ip address
encapsulation ppp
dialer rotary-group 1
dialer-group 1
autodetect encapsulation ppp
isdn switch-type primary-net5
ppp multilink
!
interface Dialer1
ip address 10.2.30.1 255.255.255.0
encapsulation ppp
ip ospf demand-circuit
dialer in-band
dialer idle-timeout 60
dialer map ip 10.2.30.22 name CE-FAIZABAD broadcast 05278221289
dialer map ip 10.2.30.22 name CE-FAIZABAD broadcast 05278221290
dialer map ip 10.2.30.23 name CE-KANPUR broadcast 05122307760
dialer map ip 10.2.30.23 name CE-KANPUR broadcast 05122307765
dialer map ip 10.2.30.2 name DOCO-PRAGNARAYAN-LUK broadcast 2204602
dialer map ip 10.2.30.3 name DOCO-JAWAHARBHAWAN-LUK broadcast 2287630
dialer map ip 10.2.30.21 name CE-JHANSI broadcast 05172331786
dialer map ip 10.2.30.21 name CE-JHANSI broadcast 05172331758
dialer-group 1
ppp multilink
S5/7:15 is D channel for PRI. All the dialer maps used are for different physical locations. My confusion is as dialer 1 is using a /24 mask. In case I dial 2 channels for different locations then I will have 2 channels going to seperate /24 masks (physical locations). Will this cause any confusion in routing or the router or mux is intelligent enough in any sense to get it to work??
