Configuring DHCP Server using IPv6 Stateless
Configuring DHCP Server using IPv6 Stateless
The Cisco Remote PHY System supports the Stateless Address Auto Configuration (SLAAC). IPv6 address
assignment of the RPD is governed by the configuration bits set in the ICMPv6 Router Advertisement (RA)
message and the presence of a valid prefix in the Prefix Information Option (PIO). For more information
about RPD IPv6 address assignment, refer to section 6.7 of Remote PHY Specification.
To configure DHCP server using IPv6 Stateless and enable SLAAC, follow the steps below:
1. Configure Prefix Type to "stateless" in CNR prefix.
2. Configure ICMPv6 Router RA message M Bit=0 and O Bit =1.
Note
It is recommended that you follow the DHCP options listed in Table 2 - Router Advertisement M Bit and O
Bit Settings For SLAAC of section 6.7.1 (CM-SP-R-PHY-I10) or 6.6.1 (CM-SP-R-PHY-I11) in the Remote
PHY Specification.
To display the RPD get IPv6 address by SLAAC, use the show dhcp command.
