Configuring HP's Router to Interoperate
via PPP with other Major Vendor's Routers
Cisco
-----
- To set up the HP router to interoperate via PPP with a Cisco router
the following fields must be changed from their defaults:
- In the Circuits menu for the PPP circuit the "LQM Time (secs) :" field must
be set to 0. This disables link-quality-monitoring which is not
supported by Cisco.
- In the Circuits menu for the PPP circuit the "Extended (32-bit) CRC :"
field must be set to NO. Cisco does not support extended CRCs.
- The last thing that must be done is to configure the Cisco IP address as
an "Adjacent Host". This must be done due to the fact that Cisco
does not support the IP Control Protocol (IPCP) option to negotiate
IP-Addresses. To configure the Cisco IP address as an "Adjacent Host",
configure the following in the "Static Routes" menu which under the
"DoD Internet Router" menu on the HP router:
Internet Address : Cisco IP address
Type : Adjacent Host
LAN Address : <CR> Subnet Mask : IP subnet mask
Encapsulation : Ethernet
3Com
----
- To set up the HP router to interoperate via PPP with a 3Com router
the following fields must be changed from their defaults:
- In the Circuits menu for the PPP circuit the "LQM Time (secs) :" field must
be set to 0. This disables link-quality-monitoring which is not
supported by 3Com.
- In the Circuits menu for the PPP circuit the "Extended (32-bit) CRC :"
field must be set to NO. 3Com claims to support extended CRC, but
when it was configured the box kept sending frames with 16 bit CRCs.
Proteon
-------
- To set up the HP router to interoperate via PPP with a Proteon router
the following fields must be changed from their defaults:
- In the Circuits menu for the PPP circuit the "LQM Time (secs) :" field must
be set to 0. This disables link-quality-monitoring which is not
supported by Proteon.
- In the Circuits menu for the PPP circuit the "Extended (32-bit) CRC :"
field must be set to NO. Proteon does not support extended CRCs.
- The Proteon IP address must be configured as an "Adjacent Host".
This must be done due to the fact that even though Proteon claims
to support the IP Control Protocol (IPCP) option to negotiate
IP-Addresses I was unable to get it function correctly. As a result, I
had to turn off the IPCP address negotiation on the Proteon and
configure it as an "Adjacent Host". To configure the Proteon IP address
as an "Adjacent Host", configure the following in the "Static Routes"
menu which under the "DoD Internet Router" menu on the HP router:
Internet Address : Proteon IP address
Type : Adjacent Host
LAN Address : <CR> Subnet Mask : IP subnet mask
Encapsulation : Ethernet
In addition, the IP address in the PPP menu must be set to 0.0.0.0 in
order for IPCP to come up. Note, only the IP address in the PPP menu
must be set to 0.0.0.0 NOT the IP address in the "DoD Internet Router"
menu.
Other Routers in General
------------------------
- In general, to interoperate via PPP with other routers the following must
be considered:
- If the other router does not support LQM, then in the Circuits menu for
the PPP circuit the "LQM Time (secs) :" field must be set to 0.
This disables link-quality-monitoring.
- If the other router does not support extended CRCs, then in the Circuits
menu for the PPP circuit the "Extended (32-bit) CRC :" field must be set
to NO.
- If the other router does not support the IP Control Protocol (IPCP) option
to negotiate IP-Addresses, then its IP-Address must be configured as an
adjacent host.
