Refer to the exhibit. Routers R1 and R2 are IPv6 BGP peers that have been configured to support a neighbor relationship over an IPv4 internet work. Which three neighbor IP addresses are valid choices to use in the highlighted section of the exhibit? (Choose three.)

A. ::0A43:0002
B. 0A43:0002::
C. ::10.67.0.2
D. 10.67.0.2::
E. 0:0:0:0:0:0:10.67.0.2
F. 10.67.0.2:0:0:0:0:0:0

Correct Answer: ACE

Explanation:
The automatic tunneling mechanism uses a special type of IPv6 address, termed an "IPv4- compatible"
address. An IPv4-compatible address is identified by an all-zeros 96-bit prefix, and holds an IPv4 address in the low-order 32-bits. IPv4-compatible addresses are structured as follows:
ccnp19
Therefore, an IPv4 address of 10.67.0.2 will be written as ::10.67.0.2 or
0:0:0:0:0:0:10.67.0.2 or ::0A43:0002 (with 10[decimal] = 0A[hexa] ; 67[decimal] = 43[hexa] ; 0[hexa] = 0
[decimal] ; 2[hexa] = 2[decimal])
