Refer to the exhibit. Routers R1 and R2 are IPv6 BGP peers that have been configured to
support a neighbor relationship over an IPv4 internetwork.
Which three neighbor IP addresses are valid choicesto 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
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:
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])
