How can EIGRP topologies be designed to converge as fast as possible in the event of a point-to- point link failure?

Triangulated adjacencies can increase the number of neighbors that receive queries, potentially expanding the query domain rather than constraining it.

A squared adjacency pattern does not represent a recognized EIGRP design construct that limits query propagation or improves convergence speed.

Distribute lists filter routing update advertisements but do not block EIGRP query messages from propagating, so they do not effectively bound the query domain.

When EIGRP summarization is configured at a boundary router, the summary prefix has its own topology table entry independent of its component routes. If a component route goes active and triggers a query, that query does not propagate beyond the summarizing router because downstream neighbors only know the aggregate summary, effectively stopping query scope expansion and enabling faster convergence.

Injecting a default route does not create a query boundary; queries for specific prefixes still propagate through routers even when those routers also carry a default route.
