(1)如果没有配置“no bgp default ipv4-unicast”,直接在全局配置BGP邻居关系,这样ipv4地址族会默认被激活的,但是不会显示在“show run”中; (2)如果配置“no bgp default ipv4-unicast” ,address-family ipv4地址族就会自动显示出来,此时如果再建立BGP全局邻居,这条命令就会生效: (3)“no bgp default ipv4-u...
1.1.1 address-family ipv4 address-family ipv4命令用来创建BGP IPv4单播地址族、BGP-VPN IPv4单播地址族、BGP IPv4 RT-Filter地址族视图或BGP IPv4组播地址族,并进入相应地址族视图。如果BGP IPv4单播地址族、BGP-VPN IPv4单播地址族、BGP IPv4 RT-Filter地址族视图或BGP IPv4组播地址族已经存在,则直接进入BGP IPv...
bgpaddress-family的理解 概念定义: 所谓地址族,就是把ipv4、ipv6和vpnv4分成不同的“块”,对每个“块”单独进行配置,如下所示: rack1r3(配置路由器)#地址系列?IPV4AddressFamilyIPV6地址家庭IPV4AddressFamily 由于ipv6现在应用较少,所以暂时不予讨论,如果大家配置过mplsvpn,那么对ipv4和vpnv4这两个地址族应该有些...

所有命令在address family 中独立配置,独立生效,并且都拥有独立的数据库。 正常的BGP配置模式被称为NLRI模式中配置,在NLRI模式中配置的参数只对IPv4单播生效。 IOS支持四个AFI模式,为IPv4,IPv6,CLNS,VPNv4,并且IPv4和IPv6还有单播和组播之分。 思科路由器运行的BGP为version4,一台路由器只能运行一个BGP进程,并且整...
Defined values for this field are specified in RFC 1700 (Address Family Number). For example, 1 indicates IPv4; 2 indicates IPv6. The SAFI indicates the type of the NLRI field. If the AFI is 1 and the SAFI is 128, the address in the NLRI field is a BGP-VPNv4 address. Next Hop ...
在BGP的address-family下使用network命令发布本设备上IGP路由表中的路由,network发布路由不一定是直连路由,只要本地路由表中有此路由非(BGP路由)即可发布。 发布命令:network x.x.x.x mask x.x.x.x 2、通过重分发IGP路由 在BGP的BGP视图或者BGP-VPN实例视图import-routeprotocol[ {process-id|all-processes} [...
