Refer the diagram below:

29. Which command shows you the routes inside the VRF ?
PE0R1#sh ip route vrf Cust_site1

Routing Table: Cust_site1
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

30. What does 'address-family ipv4' mean within EIGRP & RIP ?

PE0R1#sh run | se eigrp
router eigrp 1
 auto-summary
 !
 address-family ipv4 vrf Cust_site2
  network 10.0.0.0
  no auto-summary
  autonomous-system 15
 exit-address-family

 PE0R3#sh run | se rip
router rip
 version 2
 !
 address-family ipv4 vrf Cust_site1
  network 10.0.0.0
  no auto-summary
 exit-address-family

 31. How do you link an OSPF process to a specific VRF ?
 32. How to enable BGP within address-family ?

router ospf 101 vrf Cust_site1
 log-adjacency-changes
 network 10.1.14.0 0.0.0.255 area 0

 32. How to enable BGP within address-family ?
