On Router 1

The document outlines access control lists (ACLs) configured on three routers, specifying permitted and denied traffic for various protocols and hosts. Router 1 has multiple ACLs for UDP, TCP, and ICMP traffic, while Routers 2 and 3 have simpler configurations focusing on host access. Each router implements access-class restrictions for virtual terminal lines and applies specific ACLs to their interfaces.
