11-48 MAX 6000/3000 Network Configuration Guide
Setting Up Virtual Private Networks
Configuring Virtual Routers
operates as the global VRouter. Its group includes any interfaces that are not explicitly grouped
with a defined VRouter.
Figure 11-11. Typical VRouter implementation
Before Lucent Technologies introduced VRouters, the MAX unit maintained a single IP
routing table that enabled the router to reach any interface. In that context, each interface
known to the system required a unique address.
With VRouters, addresses must be unique within the VRouter’s routing domain, but not
necessarily within the MAX unit. Because each VRouter maintains its own routing table, and
because it knows about only those interfaces that explicitly specify the same VRouter, private
networks do not maintain unique address spaces.
Current limitations
SNMP management does not present a view of the MAX on a per-VRouter basis. Errors and
events are not logged on a per-VRouter basis. The Syslog host defined in the system’s Log
profile must be accessible to the main VRouter.
Only the main VRouter supports ATMP, PPTP, and OSPF.
Accessible Vrouter profiles
The servers and clients you specify in the following profiles must be accessible to the main
VRouter:
• Accounting
• Auth
• BOOTP Relay
• Call logging
• DHCP options
• Log
• Multicast
• RADIUS Server
• SNMP Options and SNMP Traps
