우리 건물에는 Cisco 라우터와 스위치가 많이 있습니다. 기본적으로 모든 건물에는 하나의 라우터와 하나 이상의 스위치가 있습니다. 각 건물에 두 개의 VLAN을 사용합니다. VLAN1은 데이터 VLAN (기본)이고 VLAN200은 음성 VLAN입니다. 각 스위치의 VLAN은 해당 건물의 라우터 (802.1q)의 서브 인터페이스에“연결”되어 있으며 모든 스위치에서 라우터의 서브 인터페이스에 연결된 포트는 트렁크 포트로 구성되어 있으므로 두 개의 VLAN 인접성이 있습니다.
문제는 IOS 12.2 스위치가 원격 서브넷에 도달 (ping)하려고 할 때 올바른 VLAN 인터페이스를 "선택"할 수 있다는 것입니다. 모든 스위치에는 192.168.X.0/24
데이터와 10.10.X.0 /24
음성이 있으므로 ping을 시도 192.168.1.2
하면 스위치는 192.168.20.2
소스 핑의 인터페이스로 VLAN 인터페이스 ( )를 사용하고 콜 관리자 ( 10.10.254.1
) 를 핑하려고 하면 스위치는 VLAN 인터페이스 10.10.248.2
를 소스로 사용합니다 .
구성이 동일하고 동일한 종류의 라우터에 연결된 IOS 15 (신규) 스위치 (IOS 12.2 스위치)는 올바른 VLAN 인터페이스를 사용하지 않습니다. 그들은 항상 음성 VLAN 인터페이스 (내 경우에는 200)를 사용하므로 원격 장치 (원격 대상 서브넷에 따라)에서 응답을 받으려면 소스 인터페이스를 선택해야합니다. 기본적으로 동일한 구성을 사용하지만 다른 위치에서 이상한 동작이 발생합니다. 새 스위치는 "dual-ipv4-and-ipv6"템플릿을 사용하고 이전 스위치 (12.2)는 "desktop default"템플릿을 사용합니다. 라우터가 패킷을 올바른 대상으로 라우팅하기 때문에 스위치 뒤에있는 컴퓨터에는 연결 문제가 없지만 스위치가없는 이유는 무엇입니까? 어떤 생각?
스위치가 "sh sdm prefer"명령의 결과 아래에서 라우팅을 지원하는지 확실하지 않습니다.
default Default bias
dual-ipv4-and-ipv6 Support both IPv4 and IPv6
lanbase-routing Supports both IPv4 and IPv6 Static Routing
qos QoS bias
이것이 스위치 구성입니다.
