Zorluk: KolayFloating Static Routes

A router receives its primary path to the 172.20.0.0/16 subnet via internal EIGRP. Which administrative distance value should be configured on a static route to ensure it functions as an inactive floating backup route until the primary path fails?

  1. A
    1
  2. B
    10
  3. C
    90
  4. 95Cevap

Cevap

An administrative distance value of 95 should be specified for the static route.
A floating static route is designed to serve as a backup path that only installs into the IP routing table when the primary route fails. Router forwarding decisions prioritize routes with lower administrative distance (AD) values. Internal EIGRP has a default AD of 90. Assigning a value of 95 ensures the static route has a higher AD than the primary EIGRP route, keeping it dormant until EIGRP route failure occurs.

Adım Adım Çözüm

1
Identify the administrative distance of the primary routing protocol.
Internal EIGRP has a default administrative distance (AD) of 90.
Routers use administrative distance to evaluate trustworthiness when selecting the best path among different routing sources.
2
Determine the required administrative distance for a floating static backup route.
The backup static route must have an AD greater than 90 (e.g., 95).
A floating static route remains inactive in the routing table only if its administrative distance is higher than that of the active primary routing protocol.
