Connecting To Other Routers - NETGEAR RT210 Reference Manual

Reference Guide for the Model RT210/RT211 ISDN Routers

Connecting to Other Routers

When connecting LANs together, you might require each end of the WAN link to be attached to a
router from a different manufacturer. Even though the NETGEAR Model RT210 and Model
RT211 ISDN routers can operate with routers from other manufacturers, not all the flexibility and
functionality are available.
The options of connecting to other routers are:
• NETGEAR to NETGEAR on IP networks
NETGEAR to NETGEAR connections are very efficient. Connecting this way lets you use the
advanced ISDN capabilities of the NETGEAR Model RT210 and Model RT211 ISDN routers
for routing between networks.
• NETGEAR to third-party router using Point-to-Point Protocol (PPP)
Connecting NETGEAR products to other products using PPP is the simplest but least efficient
implementation. PPP does not have a mechanism for arbitrating certain features such as
compression. This minimal feature implementation was developed by the IP community and
adopted for router interoperability. If using PPP, the NETGEAR router can also use PAP and
CHAP for security.
