address, the selector, are assigned dynamically after the router is activated (and
may change if the configuration of the router changes), unless you have configured
a specific selector.
Youcan specify the ATM address, including selector, by entering prot arp at the
talk 6 Config> prompt, followed by add atm, giving the desired IP address and then
specifying a selector. This is the same procedure used to define anATMARP client.
Using NHRP with LAN Emulation
If you want to use NHRP on the device, you must configure all LECs with a unique
locally administered MAC address (LAA). If you do not configure the LECs with
unique LAAs, the NHRP shortcut capability to the corresponding switch or device
will not work because:
vTraffic sent over an NHRPLANE shortcut VCC will contain the router Universally
Administered (universally administered) MAC address as the source MAC
address.
vSome network devices learn the association between the MAC address and the
VCC from traffic the device has received. These devices then use the NHRP
VCC to transmit data.
vIf the router detects incoming traffic on an NHRP VCC, it will assume that an
error condition has occurred and will shut down that VCC, preventing any further
shortcuts to that network device.
Note: By default, the router enables IBM LAN Emulation Extensions on NHRP,so
you must either disable the extensions or configure the unique locally
administered MAC address for each LEC.
