Drag and Drop Question Drag and drop the characteristics from the left onto the routing protocols they describe on the right. Answer:
The correct answer is EIGRP: hello packets are sent by default every 5 seconds on high-bandwidth links; EIGRP: metric is calculated using bandwidth and delay by default; OSPF: uses virtual links to link an area that does not have a connection to the backbone; OSPF: default cost is based on interface bandwidth only. EIGRP sends hello packets every 5 seconds on high-bandwidth links (and every 60 seconds on low-bandwidth links) and calculates its composite metric using bandwidth and delay by default (though load, reliability, and MTU can also be included). OSPF uses virtual links to connect an

Correct arrangement
- EIGRP: hello packets are sent by default every 5 seconds on high-bandwidth links
- EIGRP: metric is calculated using bandwidth and delay by default
- OSPF: uses virtual links to link an area that does not have a connection to the backbone
- OSPF: default cost is based on interface bandwidth only
Explanation
EIGRP sends hello packets every 5 seconds on high-bandwidth links (and every 60 seconds on low-bandwidth links) and calculates its composite metric using bandwidth and delay by default (though load, reliability, and MTU can also be included). OSPF uses virtual links to connect an area that lacks a direct physical connection to the backbone Area 0, and its default cost is based solely on interface bandwidth (reference bandwidth divided by interface bandwidth).
