BGP Configuration and Troubleshooting FAQ
1. Which BGP routers will become peers and share routing information?
BGP routers that are configured with the neighbor command.
2. Refer to the exhibit. BGP sessions are established between all routers. RTC receives route updates for network 209.165.200.224/27 from autonomous system 300 with the weight attribute set to 3000. RTB also learns about network 209.165.200.224/27 from autonomous system 200 with a weight of 2000. Which router will be used by RTA as a next hop?
RTB because of the shortest

Router
Router: A device in computer networks designed to interconnect networks. Its main function is to determine the best route to send packets, using its routing table, and then send those packets to their destination.
Memory Types
- RAM: Executes instructions stored in CPU time (volatile). It saves:
- The IOS, unzipped from flash memory at startup.
- The configuration file in execution (running-config).
- The routing table.
- The ARP cache.
- Packet buffers.
- ROM: Permanently stores firmware, including:
- Bootstrap
IPv6, NAT, and PAT Configuration
This document covers several key concepts related to IPv6, Network Address Translation (NAT), and Port Address Translation (PAT).
1. IPv6 EUI-64 Identifier
Refer to the exhibit. The IPv6 address 2006:1::1/64 with EUI-64 has been configured on the router’s FastEthernet0/0 interface. Which statement accurately describes the EUI-64 identifier configuration?
The configuration will derive the interface portion of the IPv6 address from the MAC address of the interface.
2. Inside Global Address
