Configuration of IP Telephony nodes using OTM 2.2 Page 479 of 910
IP Line Description, Installation and Maintenance
The default route on the card causes packets for unknown subnets to be
sent out on the TLAN network interface. Packets from an external host
arrive on the ELAN network interface and responses are sent on the
TLAN network interface. This can cause one-way communication if the
TLAN subnet is not routed to the ELAN subnet. It is necessary to add an
entry in the Route list, to correct the routing so that response packets are
sent on the ELAN network interface. Each entry creates a route entry in
the card's route table that directs packets to the ELAN network interface.
See Figure 152 on page 480.
6To add a net route or host route, type the IP address and subnet mask in
the entry field of the card routing table, and click Add.
7Click Apply.
CAUTION
Use caution when assigning card routing table entries.
Do not include the IP address of an IP Phone. Otherwise,
voice traffic to this IP Phone is incorrectly routed through
the ELAN network interface and ELAN gateway. To
avoid including the wrong IP address, Nortel
recommends that Host IDs be defined for the card
routing table entries.
