Q

In XPL, matches-every (11:10, 11:11, 11:12) requires that all communities are marked on the prefix to match.

A

True, a prefix with only 1 or 2 of the communities will not match

17
Q

What command to view the route-policy AS65-IN as well as all other rpl objects associated with it?

A

show rpl route-policy AS65-IN detail

18
Q

How can the policy test be tested? In which direction does the command test?

A

show bgp route-policy test, Direction in

19
Q

What are the default seed metrics for RIP and EIGRP?

A

infinite except when the source is static or connected

20
Q

What is the default seed metric for redistributed routes in IGP > OSPF? What type of route?

A

Metric 20 when the source is other IGP, except when the source is another process

21
Q

What is the default seed metric for redistributed routes in OSPF > OSPF? What type of route?

A

The metric value is copied when the type is E1

22
Q

What is the default seed metric for redistributed routes in BGP > OSPF? What type of route?

A

Metric 1, type E2

23
Q

What is the metric value for infinite for RIP and EIGRP?

A

0

24
Q

What is the default seed metric for ISIS?

A

0, the best cost

25
Q

RIP and EIGRP redistribute a route for which the seed metric has not been defined.

A

false

26
Q

The IGP metric will be copied to the BGP MED

A

true

27
Q

In what ways can the seed metric be configured?

A

At the process level and in the redistribution command

28
Q

What are the safe conditions for one-way multipoint redistribution?

A

The destination protocol must support different metrics for external and internal routes (BGP and EIGRP), The metric for external routes in the destination protocol must be higher than the metric in the source protocol

29
Q

What are the recommended measures for two-way redistribution?

A

Only internal routes should be exchanged between protocols, Routes should be filtered based on tags, The metric should be propagated between protocols

30
Q

What is the administrative distance for connected and static routes?

A

0 and 1

31
Q

What is the administrative distance for Internal EIGRP, External EIGRP, and Summary EIGRP?

A

90, 170, and 5

32
Q

What is the administrative distance for ISIS, RIP, and OSPF?

A

115, 120, and 110

33
Q

What command is used to change the AD of routing protocols?

A

distance

34
Q

In OSPF, is it possible to set a different AD for external, internal intra-area, and internal inter-area routes?

A

True

35
Q

In IOS XR, it is not possible to set different ADs by address families in ISIS.

A

false, it is possible
