PCR: 03527 Module: BGP Level: 4

Session-only counters have been added to the MIB entry for BGP peers.

PCR: 03622 Module: ENCO Level: 2

Interoperating with other vendors implementations of ISAKMP was occasionally causing errors following key exchanges. This relates to differing implementations of the RFC regarding the retention of leading zeros. This issue has been resolved by modifying the software to retain leading zeros. An additional command provides compatibility with routers that still use previous software versions. The command details are:

SET ENCO DHPADDING={ONOFF}

This command controls the padding process for Diffie Hellman generated values. This may be required when interoperability is required with other vendor’s equipment that uses the Diffie Hellman algorithm.

The DHPADDING parameter specifies whether the Diffie Hellman generated values should be padded or not. If ON is specified, then leading zeros will be inserted into the generated values. If OFF is specified, then the generated values will not be padded. The default is ON.

For example, to turn off the Diffie Hellman padding, use the command:

SET ENCO DHPADDING=OFF

Also, the output of the SHOW ENCO command now contains a new line showing the setting for DHPADDING.
