Figure 240 Network for the DCC application providing logic interface standby through dialer route

	Modem 8810059	8810060	Modem
		PSTN
Serial0			Serial0
Router A	Serial1		Serial1
			Router B

Solution 1:

Adopt circular DCC and use the logic interface configured through the dialer route command as the standby interface.

1Configure RouterA:

[Router] dialer-rule 1 ip permit

[Router] interface serial 0 [Router-Serial0]physical-mode async

[Router-Serial0] modem

[Router-Serial0]ip address 100.1.1.1 255.255.255.0

[Router-Serial0]dialer enable-circular

[Router-Serial0] dialer-group 1

[Router-Serial0]dialer route ip 100.1.1.2 8810060 logic-channel 1

[Router-Serial0]interface serial 1

[Router-Serial1]ip address 200.1.1.1 255.255.255.0

[Router-Serial1] link-protocol ppp

[Router-Serial1]standby logic-channel 1

2Configure RouterB:

[Router] dialer-rule 2 ip permit

[Router] interface serial 0 [Router-Serial0]physical-mode async

[Router-Serial0] modem

[Router-Serial0]ip address 100.1.1.2 255.255.255.0

[Router-Serial0]dialer enable-circular

[Router-Serial0] dialer-group 2

[Router-Serial0]dialer route ip 100.1.1.1 8810059 logic-channel 1

[Router-Serial0]interface serial 1

[Router-Serial1]ip address 200.1.1.2 255.255.255.0

[Router-Serial1] link-protocol ppp

[Router-Serial1]standby logic-channel 1

Solution 2:

Adopt circular DCC and use the logical interface configured through the dialer route command as the main interface.

1Configure RouterA:

[Router] dialer-rule 1 ip permit

[Router] interface serial 0 [Router-Serial0]physical-mode async

[Router-Serial0] modem

[Router-Serial0]ip address 100.1.1.1 255.255.255.0

[Router-Serial0]dialer enable-circular

[Router-Serial0] dialer-group 1
