VPN ID
*1:a < 2,000. a + b + c > 4,000
a: Number of LSPs to be Ingress, b: Number of LSPs to be Core, and c: Number of LSPs to be Egress.
*2: Maximum of 255 before Ver. 05-02
*3: If ATM is used as a backbone line, the number of LDP sessions is one per VP. Therefore, the number of LDP
sessions depends on the maximum VP value.
*4 If ATM is used as a backbone line, the LSP is allocated to VC. Therefore, the number of LSPs depends on th
maximum VC value. The ATM determines whether VCIs of an odd number shall be used or VCIs of an even num
shall be used when the LDP session is established. Therefore, if the number of LSPs to be established is not th
same in both directions, the number of VCs to be defined will be greater than the number of LSPs to be actually u
In addition, if the number of VCs per line exceeds 1024 when the statistic function of the MPLS is used, some of
VC statistics may not be acquired. It is recommended to make the number of VCs per line smaller than 1023.
*5: In a case where the number of LDP sessions is 20 or more, if a condition is made that the MPLS event log
information is indicated by the mpls monitor start command, impediment to the RP/line may occur, or if close/free
performed, the other LDP session may collapse and the LSP may be disconnected. It is recommended that no
condition should be made that the MPLS event log information is indicated by the mpls monitor start command w
the number of LDP sessions is greater than 20.
