Implement Cisco L3 Switch for EPC (SGi,S5,S6a Interface)

Here are complete config on Cisco layer 3 switch (L3_Switch) in Core Network (EPC) for implement SGi,S5,S6a Interface. I have posted config for Implement S11 Interface.

Please refer to LTE Interface and Virtual Routing for picture.

#### Parameter (S11, SGi, S5, S6a)

L3_Switch (Cisco)

Ethernet0/1: S11_MME

Ethernet0/2: S11_SGW

Ethernet0/3: S11_DNS

Ethernet0/4: S6a_HSS

Ethernet0/5: S6a_MME

Ethernet0/6: S5_SGW

Ethernet0/7: S5_PGW

Ethernet0/8: SGi_PGW
