The configuration involves connecting two buildings over fiber using OM4 cabling with a distance of 200 meters. The current optics in use are 25GR (25 Gigabit Rate) optics.

For multimode fiber such as OM4, SR (Short Reach) optics are suitable for distances up to 300 meters. In contrast, LR (Long Reach) optics are typically designed for single-mode fiber and longer distances.

Therefore, to properly support the 200m OM4 fiber link, 25SR optics should be used instead of 25GR (which are often long-reach optics).

10SR and 10LR refer to 10Gbps optics, which do not meet the 25Gbps requirement.

25LR optics are for single-mode fiber and longer distances, not multimode.

When configuring OSPF on a point-to-point network type (typically a direct link between two routers), OSPF treats the link as a broadcast-less point-to-point segment.

This reduces unnecessary OSPF overhead by eliminating the need for:

DR/BDR elections (which generate LSA Type 2 advertisements for broadcast multi-access networks).

Thus, changing network type to point-to-point reduces the number of LSA Type-2 advertisements, which are used to describe the network segment in multi-access environments.

No impact on number of routes (LSA Type-3 is about inter-area routes).

The default is usually broadcast or point-to-multipoint depending on interface.

The multicast group address 239.0.0.1 falls within the administratively scoped multicast addresses but overlaps with the Link-Local Multicast address scope (224.0.0.0/24), which is reserved for protocol control traffic and should not be used for application multicast groups. Using an address that overlaps with the Link-Local scope can cause multicast routing and forwarding issues, leading to video streaming clients not receiving the stream.

IGMP snooping version or enabling IGMP without multicast traffic do not cause this issue.

PIM-SM discovery addresses are different multicast addresses.
