What is the maximum number of parallel routes that can be injected into the routing table when using the iBGP multipath load sharing feature?

A.
iBGP multipath can support up to 4 parallel paths.

B.
iBGP multipath can support up to 6 parallel paths.

C.
None, multipath is supported on eBGP only when used in conjunction with the update-source command.

D.
The number of parallel paths injected into the routing table will depend on the IGP currently in use within the iBGP domain.

E.
The maximum number of parallel paths injected into the routing table is specified by BGP MED and ranges from 2 to 256 parallel paths.
