Before You Configure Shared Interfaces
Before you configure shared interfaces, remember that
on the Root System Domain (RSD), you configure the physical SONET
interface and then configure and assign each logical shared interface
under it to a specific Protected System Domain (PSD).
On the PSD, you configure the physical SONET interface as well
and identify it as a shared interface. Then configure the assigned
logical interfaces under it and bind each one to a peer interface
on the Tunnel PIC owned by the PSD.
When you configure shared interfaces, the values for several
parameters configured on the RSD and the PSD must match:
- Frame Relay encapsulation must be configured on the physical SONET
interface in both the RSD and PSD.
- The same maximum transmission unit (MTU) size must be
used on the physical SONET interface in both the RSD and PSD. For
example, in both the RSD and PSD, do not include any MTU configuration
to allow the default MTU size to be applied to the physical interface.
Or, in both the RSD and PSD, configure the same MTU size. For example,
in both the RSD and PSD configuration, include the mtu 5000 statement under the [edit so-0/0/1] hierarchy level.
- The same
logical unit number must specified on the physical SONET interface
(so-fpc/pic/slot.logical unit-number) and
on the physical uplink tunnel interface (ut-fpc/pic/slot.logical
unit-number) owned by the PSD. For example, in both
the RSD and PSD configuration, specify so-0/0/0.1 as the
logical SONET interface. In the PSD configuration, configure ut-0/0/0.1 as the logical peer tunnel interface.
- The same data-link connection identifier (DLCI) must be specified
on the logical SONET interface configured in both the RSD and the
PSD. For example, at the [edit interfaces so-0/0/0.1] hierarchy
level, include the dcli 101 statement in both the RSD configuration
and in the PSD configuration.
