Applying an ATM Service Class
After defining a service class on SSR1 and SSR2, apply them to the VC connection we
created earlier.
The following command line applies the service class ‘cbr1m’ to the VC (vpi=0, vci=100)
on ATM port at.1.1 of SSR1:
The following command line applies the service class ‘cbr1m’ to the VC (vpi=0, vci=100)
on ATM port at.2.1 of SSR2:
Configuring an Interface on an ATM Port
The next step is to configure an interface for each ATM port. Creating an interface on an
ATM port assigns a network IP address and submask on that port, and assigns it to a
specified VC (VPI/VCI pair). Since a VC is a connection in the ATM Layer only, creating
an interface for an ATM port is necessary to establish a connection in the IP network layer.
You can assign a peer-address to an ATM port interface. This peer-address specifies the IP
address for the other end of the VC connection.
Set the IP interface name as ‘atm1’ and IP address as 11.1.100.1/24 on ATM port
at.1.1.0.100. The following command line configures the interface on SSR1
:
Set the IP interface name as ‘atm2’ and IP address as 11.1.100.2/24 on ATM port
at.2.1.0.100. The following command line configures the interface on SSR2
:
Configuring an IP Route
The next step is to add an IP route which will specify a gateway address to reach a certain
subnet. You already configured IP interfaces for both Ethernet ports. VLAN B (connected
to IP interface 11.1.2.1/24) belongs to the subnet 11.1.2.0. Similarly, VLAN A (connected to
IP interface 11.1.1.1/24) belongs to the subnet 11.1.1.0.
ssr1(config)# atm apply service cbr1m port at.1.1.0.100
ssr2(config)# atm apply service cbr1m port at.2.1.0.100
1(config)# interface create ip atm1 address-netmask 11.1.100.1/24 peer-
address 11.1.100.2/24 port at.1.1.0.100 up
ssr2(config)# interface create ip atm2 address-netmask 11.1.100.2/24
peer-address 11.1.100.1/24 port at.2.1.0.100 up
