A: The OSFP is a pluggable form factor with 8x high speed electrical lanes that support up to 400 Gbps (8x50G), 800 Gbps (8x100G), or 1. Up to 36 OSFP ports are supported in 1 U front panel. Q: What are the variants of the OSFP form factors?EXTREMEPORT™ OSFP CONNECTOR AND CAGE SYSTEMS SUPPORTING 56G, 112G & 224G Amphenol's ExtremePort™ OSFP connector and cage family delivers a scalable, high-performance interconnect platform designed for next-generation data centers, high-density switch/router systems, and high-speed serial. OSFP-XD MSA Rev 1. 11 Specification for OSFP-XD Octal Small Form Factor eXtra Dense Pluggable Module is posed in the specification section of the website, to correct the figure 4-11 in the OSFP-XD MSA Rev 1. and a disclaimer is added to the Other Documents section. OSPF also allows packet authentication and uses IP multicast when sending and receiving packets. The Cisco implementation supports RFC 1253. This specification defines the electrical connectors, electrical signals and power supplies, and mechanical and thermal requirements of the OSFP and OSFP-RHS module, connector, and cage systems. It uses 8 lanes at 50G PAM4 (400G) or 100G PAM4 (800G) with a 60-pin edge connector. TE Connectivity's OSFP series supports up to 36 ports in 1RU switches while delivering superior. OPT 1 - an area per stack with the both DIST in area 0 along with the core OPT 2 - all DIST and access in area 1 Looking at best practice docs, i believe Cisco would recommend option 2? but that to me makes a busy area 1? thoughts? Thanks 07-19-2016 07:37 AM Hi, Normal OSPF deign best practice.
