Chapter 6 Cabling the Line Ports and Completing the Installation
The actual connections might look like this:
Router 1: S=0/1, Cisco SCE 8000 #1 3/0/0
•
Router 2: S=0/1, Cisco SCE 8000 #1 3/2/0
•
Router 1: N=2/2, Cisco SCE 8000 #1 3/1/0
•
Router 2: N=2/2, Cisco SCE 8000 #1 3/3/0
•
Router 1: S=0/2, Cisco SCE 8000 #2 3/0/0
•
Router 2: S=0/2, Cisco SCE 8000 #2 3/2/0
•
Router 1: N=3/1, Cisco SCE 8000 #2 3/1/0
•
Router 2: N=3/1, Cisco SCE 8000 #2 3/3/0
•
Router 1: S=1/3, Cisco SCE 8000 #3 3/0/0
•
Router 2: S=1/3, Cisco SCE 8000 #3 3/2/0
•
• Router 1: N=3/2, Cisco SCE 8000 #3 3/1/0
• Router 2: N=3/2, Cisco SCE 8000 #3 3/3/0
• Router 1: S=1/5, Cisco SCE 8000 #4 3/0/0
Router 1: S=1/5, Cisco SCE 8000 #4 3/2/0
•
Router 1: N=3/4, Cisco SCE 8000 #4 3/1/0
•
Router 1: N=3/4, Cisco SCE 8000 #4 3/3/0

Dual Routers with N+1 Redundancy MGSCP Connectivity
To achieve N+1 redundancy, add one extra SCE platform as the standby platform. Also, add another port
on each EC to be used as standby ports. In this case, use five SCE platforms, four on the traffic links and
one for redundancy, which would be connected to the standby ports.
Again, for the sake of simplicity, assume that the EC ports are the same on both routers.
If you add ports 0/3 on EC1 and 2/4 on EC2, the ECs would look like this:
EC1: 0/1, 0/2, 0/3, 1/3, 1/5
•
EC2: 2/2, 2/4, 3/1, 3/2, 3/4
•
The standby ports must be the highest-numbered ports:
EC1 standby port: 1/5
•
EC2 standby port: 3/4
•
The traffic ports would be assigned to the links as follows:
Link 1. S=0/1, N=2/2
•
• Link 2. S=0/2, N=2/4
• Link 3. S=0/3, N=3/1
• Link 4. S=1/3, N=3/2
The standby ports would be assigned to the links as follows:
Link 5 (standby). S=1/5, N=3/4
