Routes learned through the Network mode in BGP do not necessarily have to be routing entries that exist in the IP routing table. At the same time, the routes injected in this way are more accurate.

Question

Options

• ATRUE
• BFALSE

• A
  24% (17)
• B
  76% (54)

Explanation

Option B (FALSE) is correct because BGP's network command requires an exact matching prefix to exist in the IP routing table before it will be advertised to peers - if the route is absent from the routing table, BGP simply will not advertise it. The statement's first clause is therefore factually inverted: Network mode is stricter than redistribution, not looser. The second clause (that Network-injected routes are "more accurate") is actually true in isolation, but since the full compound statement contains a false premise, the entire statement is false. Option A is wrong because it accepts a claim that directly contradicts how BGP Network mode works - route presence in the RIB is a hard prerequisite, not optional.

Memory tip: Think of the network command as a bouncer checking a list - if the exact prefix isn't already in the routing table, it doesn't get into BGP. "Network = No table entry, No advertisement."
