Configuring IP Exterior Gateway Protocols (BGP and EGP)

A-18

308628-14.00 Rev 00

Parameter: Tcp Md5 Key Storage

Path: Configuration Manager > Protocols > IP > BGP > Peers

Default: None if TCP Authentication is None.

Clear Text if TCP Authentication is MD5.

Options: Clear Text

Encrypted

Function: Specifies whether the MD5 authentication key is stored as clear text or

encrypted.

Instructions: Accept the default value, Clear Text to specify no encryption for the stored key.

Set this parameter to Encrypted to store the MD5 key in encrypted form. Setting

this parameter to Encrypted also makes the NPK parameter visible.

MIB Object ID: 1.3.6.1.4.1.18.3.5.3.2.5.1.2.1.46

Parameter: Node Protection Key

Path: Configuration Manager > Protocols > IP > BGP > Peers

Default: An 8-byte value. If TCP Authentication is MD5 and Tcp Md5 Key Storage is

Encrypted, this value is the one configured as the node protection key in the

wf_key_file_path environment variable.

Not used if TCP Authentication is None.

Options: ASCII character string

Function: Used as a cryptographic key for protecting sensitive MIB objects. The NPK

value is stored in nonvolatile memory (NVRAM). The IP security software

performs a hash of the NPK value, which it places in a special MIB attribute.

The NPK value stored in NVRAM is unique to the router. It is used to encrypt

the cipher and integrity keys before they are stored in the router MIB. In the

context of Border Gateway Protocols (BGP-4), if the Tcp Authentication

parameter is MD5 and the Tcp Md5 Key Storage parameter is Encrypted, the

value of the NPK is used to encrypt the Tcp Md5 Key value.

Instructions: Enter a 16-digit hexadecimal value. (Enter the prefix 0x before the 16 digits.)

This value is configurable with the WEP Key Manager > NPK Manager or with

the secure shell of the Technician Interface, as described in Configuring IPsec

Services.

MIB Object ID: None Available
