Verification
In the previous chapter, the P8
router acted as the overlapping PQ node, facilitating traffic redirection from P2
to P8
, which then routed it to the destination router, PE5
.
However, in this case, the optimal path from the P8
router to PE5
does not pass through P4
, as illustrated in the following section.
Verifying the primary path from P8 to PE5
After applying the described configuration, the primary path from P8
to PE5
explicitly passes through the P2–P3
link.
The following traceroute output illustrates that P8
utilizes the P2–P3
link to reach PE5
, as the cost of passing through the P8–P4
link is higher:
