Connecting Switches
Switches can be connected either directly, through cabling, or indirectly via a WAN. Figure 1 on page 3
shows an example of the different types of connection.
Connecting Switches Directly
When connecting two switches directly you must:
If the switches belong to the same peer group:
1. Define the two connecting ports as PNNI links
2. Ensure that the peer group id of both switches match (and are less than 104 bits in length). See
“Configuring Peer Group Identifiers” on page 62 for more information.
If the switches do not belong to the same peer group:
1. Define the two connecting ports as IISP links
Example:
The following example shows how to connect two switches in different PNNI peer groups.
Figure 4. Connecting Switches in Different Peer Groups
This example shows how to connect Switch 1 in Peer Group A to Switch 2 in Peer Group B (using slot 6
port 1, of Switch 1 and slot 4 port 2 of Switch 2).
Assuming the network prefix of Switch 1 in peer group A is 39.99.99.99.99.99.99.00.00.99.99.01, and the
network prefix of Switch 2 in peer group B is 39.99.99.99.99.99.99.00.00.99.99.02, then:
1. On Switch 1, you would enter the commands:
à
ð
8265ATM
>
set port 6.1 enable iisp user
8265ATM> set reachable_address 6.1 96 39.99.99.99.99.99.99.ðð.ðð.99.99.ð2
á
ñ
2. On Switch 2, enter the commands:
à
ð
8265ATM
>
set port 4.2 enable iisp network
8265ATM> set reachable_address 4.2 96 39.99.99.99.99.99.99.ðð.ðð.99.99.ð1
á
ñ
This is using the default VPI=0. If the VPI is not 0, you must define the VP at the end of the set reachable
address, and set the port signalling version accordingly.
