____________________________________________________________________

▪ IPv6 HSRP

- IPv6의 경우 HSRP를 구성할 때 반드시 HSRP version 2를 사용해야 한다.

 

- UDP 포트 2029번 사용한다.

 

- Virtual MAC 주소는 [0005.73A0.0NNN]을 사용한다.  NNN은 Group 번호를 의미한다.

 

- Virtual IP 주소는 Link-Local 주소가 사용되며, Autoconfig가 가능하다.

  각 Group의 Virtual MAC 주소를 사용하여 EUI-64 방식으로 Virtual IP 주소의 Interface-ID를 생성.

 

- Active 장비가 전송하는 HSRPv2 Hello 메시지의 출발지 MAC 주소는 Virtual MAC 주소가 사용된다.  Standby 장비가 전송하는 HSRPv2 Hello 메시지의 경우 출발지 MAC 주소로 실제 장비의 MAC 주소가 사용된다.

 

netsh interface ipv6 show neighbor -> ipv6 네이버 테이블 보기

netsh interface ipv6 delete neighbors -> ipv6 네이버 테이블 삭제
