EVPN VLAN-Aware Bundle Service
In the EVPN/MPLS Bridging Forwarding Model blog post I mentioned numerous services defined in RFC 7432. That blog post focused on VLAN-Based Service Interface that mirrors the Carrier Ethernet VLAN mode.
RFC 7432 defines two other VLAN services that can be used to implement Carrier Ethernet services:
- Port-based service – whatever is received on the ingress port is sent to the egress port(s)
- VLAN bundle service – multiple VLANs sharing the same bridging table, effectively emulating single outer VLAN in Q-in-Q bridging.
And then there’s the VLAN-Aware Bundle Service, where a bunch of VLANs share the same MPLS pseudowires while having separate bridging tables.

Cloudflare DDoS threat report 2022 Q3
This post is also available in Français, Español, Português, 한국어, 简体中文, 繁體中文, and 日本語.
Welcome to our DDoS Threat Report for the third quarter of 2022. This report includes insights and trends about the DDoS threat landscape - as observed across Cloudflare’s global network.
Multi-terabit strong DDoS attacks have become increasingly frequent. In Q3, Cloudflare automatically detected and mitigated multiple attacks that exceeded 1 Tbps. The largest attack was a 2.5 Tbps DDoS attack launched by a Mirai botnet variant, aimed at the Minecraft server, Wynncraft. This is the largest attack we’ve ever seen from the bitrate perspective.
It was a multi-vector attack consisting of UDP and TCP floods. However, Wynncraft, a massively multiplayer online role-playing game Minecraft server where hundreds and thousands of users can play on the same server, didn’t even notice the attack, since Cloudflare filtered it out for them.
General DDoS attack trends
Overall this quarter, we've seen:
- An increase in DDoS attacks compared to last year.
- Longer-lasting volumetric attacks, a spike in attacks generated by the Mirai botnet and its variants.
- Surges in attacks targeting Continue reading
OSPF External Routes (Type-5 LSA) Mysteries
Daniel Dib posted a number of excellent questions on Twitter, including:
While forwarding a received Type-5 LSA to other areas, why does the ABR not change the Advertising Router ID to it’s own IP address? If ABR were able to change the Advertising Router ID in the Type-5 LSA, then there would be no need for Type-4 LSA which meant less OSPF overhead on the network.
TL&DR: The current implementation of external routes in OSPF minimizes topology database size (memory utilization)
Before going to the details, try to imagine the environment in which OSPF was designed, and the problems it was solving.
