IP communication

TCP/IP Internet Protocol (IP) is a network layer protocol and the OME6130
uses IPv4. Each OME6130 shelf must have one IP address assigned to it for
management purposes. Typically, the IP address used to manage the OME6130
is the circuitless IP address. The circuitless IP is designated as Router ID.
The LAN (LAN-1-6) Ethernet interface can be assigned with a single IP
address and subnet mask. A gateway network element requires an IP address
on a different subnet to the Router ID for the Ethernet interface connected to
the external DCN.
For general information on assigning IP addresses in a network, see
networks, addressing, and masks on page
IP addressing implementation rules
You must observe the following rules when you implement the IP addresses:
•
•
•
•
•
Set the LAPD IP MTU size to 446 when interworking with Optical Metro
4000 and TN-1C family of products which has a fixed LAPD MTU of 512
bytes. The OME6130 LAPD MTU is set to 512 by default.
On a DCC interface over SDH overhead bytes, both OSPF and iISIS
routing protocols cannot be enabled simultaneously.
CAUTION
Circuitless IP (Router ID) address
The circuitless IP has a non-provisionable default subnet mask
of 255.255.255.255.
Each network element must be assigned with an IP address and subnet
mask for the LAN port, and an IP address for the circuitless IP (Router ID)
address.
For a gateway network element, you must provision an IP address for the
LAN port on a different subnet to the Router ID IP address. The LAN
interface must be assigned an IP address in the same subnet of the external
router port connected to the LAN interface of the gateway network
element.
A node reset (warm restart) on the NE is required after changing the Router
ID or Ethernet IP address in order for the new IP addresses to take effect
Overlapping IP addresses cannot be assigned.
When assigning private IP addresses, it is recommended that the IP
addresses in the range of 10.1.1.0 to 10.4.255.255 are not used. These IP
addresses are used by the OM5000 network elements for internal data
communications so should not be used in any OME6130 network that will
contain OM5000 network elements.
