Configuring the Routers
The following needs to be added to the enterprise edge routers:
● GRE tunnel interfaces that will connect to the USTAT modules
● route maps for policy routing on the tunnels
● outing between the edge routers and the CNA system, including iBGP peering and
● routing to the USTAT VIPs
For the purposes of describing the CNA configuration process using widely understood
terminology, this documentation assumes a simple, generic network that uses Cisco equipment
as its edge routers and Cisco IOS commands.
Edge Router GRE Tunnel Interfaces
Each CNA USTAT module needs to be associated with a different tunnel interface on the Cisco
router. Referring back to the example in Figure 95
, three tunnels are needed. Since there are
three USTAT modules and only two edge routers, two of the tunnels—Tunnel1 and
Tunnel2—will be created on the one edge router, while the third tunnel—Tunnel3—will be
created on the other edge router.
