Filter-policy can be used on an ASBR in OSPF to filter Type 5 and Type 7 LSAs.

Filter-policy can filter received or advertised link state information, and route attributes can be modified.

Only the default routes match the IP prefix list configured using the ip- ip-prefix 1 deny 0.0.0.0 less-equal 32 command.

Question 85

Type 5 LSAs in OSPF are used to transmit external routes. Which of the following statements regarding Type 5 LSAs is false?

Type 5 LSAs are advertised by ASBRs and flooded on OSPF networks except stub areas and NSSAs.

Filtering policies can be configured on ABRs or ASBRs to filter Type 5 LSAs.

A Type 5 LSA contains the FA address, which is 0.0.0.0. The FA address is reserved only and does not take effect.

Routers in the same area as the ASBR can calculate external routes through intra-area LSAs and Type 5 LSAs.

Question 87

Which of the following statements regarding BGP confederations is false?

By default, sub-AS numbers of a confederation are advertised to BGP peers outside the confederation.

A BGP confederation divided an AS into several sub-Ass. Ass outside a confederation still consider the confederation as an AS.

Confederations can easily detect routing loops inside an AS because EBGP is run between sub-AS's.

Sub-Ass within a BGP confederation can use private AS numbers. For Huawei NE and AR routers, a maximum of 32 sub-Ass can be configured in a BGP confederation.
