In a redundant hub-and-spoke design with inter-spoke links, load oscillation and routing instability occur due to overload conditions. Which two design changes improve resiliency? (Choose two)
A.
Increase the number of redundant paths considered during the routing convergence calculation
D: Increasing unequal-cost multipath (UCMP) paths allows the routing protocol to load-share over more than one path, preventing traffic congestion from oscillating between nodes.
E: Dual links to each site improve bandwidth and failover options, reducing reliance on overloaded peers.
Other options:
A: Increasing redundant paths may worsen convergence complexity and doesn't solve oscillation.
B: Removing inter-spoke links reduces redundancy.
C: Increasing convergence timers delays recovery and stability.
