Ethernet types:
Layer 2 MAC filtering is implemented at JIX to help prevent unauthorised traffic from entering the exchange, each peering port/bundle is restricted to a single MAC address.
Unicast only (except for broadcast ARP and Neighbour Discovery/IPv6 Things)
The following protocols are fine:
Please assume all others are a no-no
The JIX route server system also provides well known communities to allow members to control the distribution of their prefixes. These communities are defined as follows:
Community | Description |
---|---|
0:peer-as |
Prevent announcement of a prefix to a peer |
24224:peer-as |
Announce a route to a certain peer |
0:24224 |
Prevent announcement of a prefix to all peers |
24224:24224 |
Announce a route to all peers |
So, for example, to instruct the route server to distribute a particular prefix only to AS64111 and AS64222, the prefix should be tagged with communities: 0:24224
, 24224:64111
and 24224:64222
.
Alternatively, to announce a prefix to all JIX members, excluding AS64333, the prefix should be tagged with community 0:64333
.
