This network comprises:
• 1 ADR, release P1 or P2 : ADR 4
• 3 ADRs, release P3 : ADR 1, 2 and 3
• 1 FOTC : FOTC 1
The PPP links respectively connecting ADR 4 and ADR 2 and ADR3 must be numbered links.
The PPP links between ADR1,ADR2,ADR3 will be preferentially unnumbered links.
Equipment addressing:
The Ethernet network forms an IP sub-network.
Each of the numbered PPP links forms an IP sub-network.
The addresses of ADR 1, 2, 3 (equipment address) can be selected in any given way (but not in
the Ethernet sub-network).
This leads us to define:
• A sub-network per numbered ppp link, with each end of the link having a separate address
(sub-networks 3, 4 and 5)
• A sub-network for the virtual interfaces of the ADRs connected by an unnumbered link. (1)
• A sub-network for the Ethernet network (2).
