Name 3 ways to filter Type 3 LSAs
|
Distribute-list
area x filter-list / area x range n/n not-advertise |
Describe the area x filter-list / command
|
It goes under the router ospf process, when using the "in" keyword you will be filtering type 3 LSAs going into the configured area. "out" keyword is for filtering type 3 LSAs coming out of the configured area.

What are three ways to prevent suboptimal routing when using mutual redistribution at multiple routrers?
|
Administrative Distance
Route Tags Metrics & Metric Types |
Under RIP, EIGRP and IS-IS routing process, how does the "distance" command work?
|
distance {distance-value ip-address {wildcard-mask} [ip-standard-list] [ip-extended-list]
-the AD to be set, the IP address of the router advertising the routes, optionally, an ACL which matches routes. With these routing protocols "ip-address" parameter identifies the neighboring router's interface address. |
Under OSPF routing process, how does the "distance" command work?
|
distance {distance-value ip-address {wildcard-mask} [ip-standard-list] [ip-extended-list]
-the AD to be set, the IP address of the router advertising the routes, optionally, an ACL which matches routes. With OSPF routing protocols "ip-address" parameter identifies the RID of the router owning (creating) the LSA for the route. |
When using Route Tags to prevent suboptimal routing loops, you should tag all routes taken from the ________ AD domain and advertise INTO the _________ AD domain.

What is a negative side effect of tagging and filtering redistributed routes?
|
The redistribution routers don't have the alternate route due to the fact that they filtered the routing advertisement. Although, internal routers will.
|
How is the BGP router ID determined?
|
In order:
The bgp router-id command The highest IP of an up/up loopback at the time that the BGP process starts. The highest IP of another up/up interface at the time the BGP process starts. |
