3Com Router 3000 Ethernet Family
Configuration Guide
On Router A create a static net-to-net NAT entry, translating network address
10.1.1.0/24 to 211.2.1.0/24; and configure dynamic routing, ensuring the route to
211.2.2.0/24 is reachable.
Likewise, on Router B create a static net-to-net NAT entry, translating network
address 10.1.1.0/24 to 211.2.2.0/24; and configure dynamic routing, ensuring the
route to 211.2.1.0/24 is reachable.
