Refer to the Exhibit.
The IGP is IS-IS. R2 has configured its loopback interface in Level 2 only. Referring to the exhibit, which statement is true?
A.
R2 advertises its loopback address to all L1 adjacencies.
B.
R1 cannot reach R2’s loopback address.
C.
R1 uses a default route to reach R2’s loopback address.
D.
R1 automatically selects R2 as the default gateway to reach R2’s loopback address.
Without asking them to delete it, is there a way i can delete my own blog comments on someone else’s blog? Please help(:.
Can someone explain these ISIS questions diagrams which show L1 links between two different ISIS areas? All ISIS documentation indicates that inter-area links must be L2.
A bit misleading in the doc (or hidden .. depends on your view point) where R2, R3, R4 and R5 are L1-L2 routers.
Could be that those routers have multiple ISO addresses configured (or not) but for L1 to L1-L2 router adjacency , iso address / area ID need to match.
Diag does not show the label “L1-L2” on the links between R1-R2, R1-R4, R3-R6, R5-R6 which can be a bit confusing. HTH.
