4.1. Intra-AS I-PMSI A-D route
+-----------------------------------+
| RD (8 octets) |
+-----------------------------------+
| Originating Router's IP Addr |
+-----------------------------------+
4.2. Inter-AS I-PMSI A-D route
+-----------------------------------+
| RD (8 octets) |
+-----------------------------------+
| Source AS (4 octets) |
+-----------------------------------+
4.3. S-PMSI A-D route
+-----------------------------------+
| RD (8 octets) |
+-----------------------------------+
| Multicast Source Length (1 octet) |
+-----------------------------------+
| Multicast Source (Variable) |
+-----------------------------------+
| Multicast Group Length (1 octet) |
+-----------------------------------+
| Multicast Group (Variable) |
+-----------------------------------+
| Originating Router's IP Addr |
+-----------------------------------+
The Multicast Group field contains the C-G address or C-LDP MP Opaque
Value Element (use of C-LDP MP Opaque Value Element is described in
Section "Receiving routes: mLDP as the C-Multicast protocol"). If the
Multicast Group field contains an IPv4 address, then the value of the
Multicast Group Length field is 32. If the Multicast Group field
contains an IPv6 address, then the value of the Multicast Group
Length field is 128.
