Keywords:MSR;ISDN;Circular DCC

I            Requirement for the diagram

Two MSR connected with E1, Apply Circular DCC.

Devices list: 2,MSR; 2,MIM-2E1; 1,E1;

CMW Version: version 5.20, Beta 1202P01, Standard

II          Network topology

Figure 1-1 Single Channel Circular DCC

III        Steps of configuration

RTA

#  sysname rta #  //Set up dialer group 1, permit IP package, and trigger dial  dialer-rule 1 ip permit #              controller E1 6/0  pri-set //Set this side clock to Master  clock master # controller E1 6/1 # interface Serial6/0:15  link-protocol ppp  ip address 10.1.1.1 255.255.255.0  //Enable circular DCC on this interface  dialer enable-circular  //Set this interface to dialer group 1  dialer-group 1  //Set dialer number facing to the other side  dialer number 6688012  //Set this side to Network side  isdn protocol-mode network

RTB

#  sysname rtb #  dialer-rule 1 ip permit # vlan 1 # controller E1 6/0  pri-set # interface Serial6/0:15  link-protocol ppp  ip address 10.1.1.2 255.255.255.0  dialer enable-circular  dialer-group 1  dialer number 6688011

IV       Key notes in the configuration

1) Set RTA to Master mode, RTB as default;

2) Set the ISDN protocol to network of interface Serial 6/0:15, RTB as default;

3) If there are other device between RTA and RTB, make sure to the woking mode of each interface, Master or Slave? Network or User.

V         Result Check

1) Ping the interface address of RTB from RTA, initiate dialer;

       [rta-Serial6/0:15]ping 10.1.1.2    

            PING 10.1.1.2: 56 data bytes, press CTRL_C to break

           Request time out

%Dec 22 11:23:28:388 2006 rta IFNET/4/UPDOWN:

            Line protocol on the interface Serial6/0:2 is UP

%Dec 22 11:23:28:398 2006 rta IFNET/4/UPDOWN:

            Protocol PPP IPCP on the interface Serial6/0:2 is UP

                Request time out

                Reply from 10.1.1.2: bytes=56 Sequence=3 ttl=255 time=26 ms

                Reply from 10.1.1.2: bytes=56 Sequence=4 ttl=255 time=26 ms

                Reply from 10.1.1.2: bytes=56 Sequence=5 ttl=255 time=25 ms

 

  --- 10.1.1.2 ping statistics ---

    5 packet(s) transmitted

    3 packet(s) received

    40.00% packet loss

    round-trip min/avg/max = 25/25/26 ms

2) Check tunnel interface state：

[rta-Serial6/0:15]dis isdn call-info

Serial6/0:15(Network-side) :

  Link Layer 1: TEI = 0, State = MULTIPLE_FRAME_ESTABLISHED

  Network Layer: 1 connection(s)

    Connection 1 :

      CCIndex:0x0002 , State: Active , CES:1 , Channel:0x00000008

      TEI: 0
