=Injecting=


 * ===__EIGRP__===
 * injects as external (EX)
 * Administrative Distance 170
 * no auto-summary
 * ===__OSPF__===
 * injects as external type 2 (E2)
 * Cost 20
 * requires "subnets" param
 * ===__RIP__===
 * injects as rip (R)
 * no auto-summary

=Logic=


 * all routes in routing table under this protocol
 * all connected subnets matched by this protocol's "network" command

=Preventing Suboptimal Routes=


 * setting administrative distance - might mess up real external routes
 * route tags

=Order of Precedence=


 * **RIP** - none
 * **EIGRP** - internal, then external
 * **OSPF** -intra-area, inter-area, E1 then E2 (if tie, cost to advertising ASBR)
 * **IS-IS** - L1, L2, then external
