You can create IPv6 ACL rules on all devices to filter BootStrap router (BSR) addresses. The devices then receive only the Bootstrap messages with the source addresses being in the valid BSR address range. Thus, BSR spoofing is prevented. ...
filter. But Strict Reverse Path Forwarding has some problems of its own. First, the test is only applicable in places where routing is symmetrical - where IP datagrams in one direction and responses from the other deterministically follow the same path. While this is common at edge network int...
当arp_filter设置为1时,如果从某张网卡上收到了一个arp请求,同时目标ip在此主机上,且不要求目标ip一定在接收到此arp请求的网卡上(<font color=navy>arp_ignore优先于arp_filter。不要求目标ip一定在接收到此arp请求的网卡,即不适用arp_ignore 1-2的情况</font>),那么主机便会查询到此请求的源ip的路由是通过...

SA filter对于SA,无论是发出去的还是收到的,无论是源自其它MSDP Peer还是自己产生的,都可以通过Filter List来做过滤,所过滤的条件可基于ACL、route map、RP access list、RP route map,这里的ACL必须是扩展ACL。 对接收的SA做过滤的命令为:ip msdp sa-filter in xxx yyy(xxx为对端MSDP路由器地址,yyy为ACL、...
