When running EIGRP, what is required for Router R1 to exchange routing updates with Router R3?
| A. |
AS numbers must be changed to match on all the routers | |
| B. |
Loopback interfaces must be configured so a DR is elected | |
| C. |
The no auto-summary command is needed on R1 and R3 | |
| D. |
Router R2 needs to have three network statements | |
| E. |
The "no passive-interface default" command is needed on all routers |
Routing updated always exchange between in same EIGRP autonomous system (AS).
It can be configured more than one EIGRP autonomous system on the same router.
So it's needed to make redistribution between different EIGRP ASs or configure all routers in one AS.
