Parameter
*.IP_Addr2
*.IP_Addr3
*.IP_Addr4
*.IP_NextHopx
Configuring Engine Parameters
For the engine to run correctly, you must modify the following parameters in the Engine section of the
XECfgParm.dat file:
Parameter
engine.CALL_MEM_BLOCK_SIZE
engine.CALL_MEM_CHUNK_SIZE Memory chunks allocated from the block of memory
OL-18083-14
XECfgParm.dat File Parameters (Specifying IP and Next Hop Router IP Addresses)
Cisco PGW 2200 Softswitch Release 9.8 Software Installation and Configuration Guide
Modification
Enter the IP address of the hme1 interface (if configured).
Enter the IP address of the hme2 interface (if configured).
Enter the IP address of the hme3 interface (if configured).
Enter the next hop router IP address.
The next hop router IP address is determined through the
*.IP_NextHopx parameter. This parameter allows you to assign
eight different next hop router addresses that are different for the
active and standby PGWs.
The *.IP_NextHopx parameter (where x is any number from 1
to 8 because there are eight entries in XECfgParm.dat) is used
with the active and standby PGWs that are on different subnets
and therefore have different IP addresses for the routers to get to
a given destination.
For every destination that needs a different next hop router, an
unused *.IP_NextHopx parameter should be chosen. The
appropriate IP address to reach the destination should be entered
in each PGW's XECfgParm.dat. If a given destination is on a
locally connected subnet of one of the PGWs, the
*.IP_NextHopx parameter for that PGW would be 0.0.0.0.
Default value: 0.0.0.0.
