Note that this is not to consider the route rejected in the advertise-map when building the summary route , but it cannot be filtered by adv-map alone.

The router goes to update the route of 3.0.0.0
Switch(config)# vlan 10
AS100 sends 10000 routes to R2 . If R2 only wants to collect 100 routes and the rest is filtered, then the general practice is to execute the in- direction filter on R2 , because AS100 is uncontrollable for AS200 . However, this method is actually a waste of link bandwidth and network resources.

In CISCO IOS 12.2(33)SXH and subsequent versions, we can deploy port-security and 802.1X on the same interface. And before this software version:

After the policy to take effect View R4 's BGP table:
The OSPF metric on R4 going to 3.3.3.3 becomes 101 , which is larger than the metric going to 5.5.5.5 . Therefore, R4 goes to
The cost value is increased, so that the OSPF metric of R4 going to 3.3.3.3 route becomes larger. What happens?

We found that both O , O IA or with the FA 's OE2 routes are redistributed into BGP later, these BGP routes Next-hop are they in OSPF the IGP next hop. At the same time, the network segment where the OSPF direct connection port is activated locally will also be injected into BGP . After the injection, Next_Hop is the router (BGP update source IP) .

At this point, the direct connection is re-released on R2 , and it is found that 1.1.1.0 has not been re-released into RIP.

Solution 1 , modify the default AD value of BGP so that its EBGP route AD value is greater than RIP to achieve the preferred purpose, but this solution may not be appropriate, because he will have an impression on all BGP routes, if only hope for 1.1.1.0 And 2.2.2.0 has an impact?

For example, if a route is flipped, the penalty value is 1000. In this case, there is a half-life ( 15 minutes). After 15 minutes (if the route is not flipped again),ccnp switch 300-115 forum, the penalty value is reduced to half 500 , and after 15 minutes, it becomes 250. At this time, if the route has another jitter, the penalty value is increased by 1000 and becomes 1250. Before this, the route is used normally. If they shake once, it becomes 2250 , exceeding the threshold 2000 , this route will be suppressed, nor not updated. After 15 minutes, if it is no longer flipped, it is reduced to half 1125 (but still suppressed), so it goes through several half-lives until it is reduced to 750 (re-use limit) and the route is enabled again.
